How to Write Topic Sentences | 4 Steps, Examples & Purpose

Published on July 21, 2022 by Shona McCombes . Revised on June 5, 2023.

How to Write Topic Sentences

Every paragraph in your paper needs a topic sentence . The topic sentence expresses what the paragraph is about. It should include two key things:

  • The  topic of the paragraph
  • The central point of the paragraph.

After the topic sentence, you expand on the point zwith evidence and examples.

To build a well-structured argument, you can also use your topic sentences to transition smoothly between paragraphs and show the connections between your points.

Table of contents

Writing strong topic sentences, topic sentences as transitions between paragraphs, topic sentences that introduce more than one paragraph, where does the topic sentence go, frequently asked questions about topic sentences.

Topic sentences aren’t the first or the last thing you write—you’ll develop them throughout the writing process. To make sure every topic sentence and paragraph serves your argument, follow these steps.

Step 1: Write a thesis statement

The first step to developing your topic sentences is to make sure you have a strong thesis statement . The thesis statement sums up the purpose and argument of the whole paper.

Thesis statement example

Food is an increasingly urgent environmental issue, and to reduce humans’ impact on the planet, it is necessary to change global patterns of food production and consumption.

Step 2: Make an essay outline and draft topic sentences

Next, you should make an outline of your essay’s structure , planning what you want to say in each paragraph and what evidence you’ll use.

At this stage, you can draft a topic sentence that sums up the main point you want to make in each paragraph. The topic sentences should be more specific than the thesis statement, but always clearly related to it.

Topic sentence example

Research has consistently shown that the meat industry has a significant environmental impact .

Step 3: Expand with evidence

The rest of the paragraph should flow logically from the topic sentence, expanding on the point with evidence, examples, or argumentation. This helps keep your paragraphs focused: everything you write should relate to the central idea expressed in the topic sentence.

In our example, you might mention specific research studies and statistics that support your point about the overall impact of the meat industry.

Step 4: Refine your topic sentences

Topic sentences usually start out as simple statements. But it’s important to revise them as you write, making sure they match the content of each paragraph.

A good topic sentence is specific enough to give a clear sense of what to expect from the paragraph, but general enough that it doesn’t give everything away. You can think of it like a signpost: it should tell the reader which direction your argument is going in.

To make your writing stronger and ensure the connections between your paragraphs are clear and logical, you can also use topic sentences to create smooth transitions. To improve sentence flow even more, you can also utilize the paraphrase tool .

As you write each topic sentence, ask yourself: how does this point relate to what you wrote in the preceding paragraph? It’s often helpful to use transition words in your topic sentences to show the connections between your ideas.

Emphasize and expand

If the paragraph goes into more detail or gives another example to make the same point, the topic sentence can use words that imply emphasis or similarity (for example, furthermore , indeed , in fact , also ).

Indeed , cattle farming alone is responsible for a large proportion of greenhouse gas emissions.

Summarize and anticipate

If the paragraph turns to a different aspect of the same subject, the topic sentence can briefly sum up the previous paragraph and anticipate the new information that will appear in this one.

While beef clearly has the most dramatic footprint, other animal products also have serious impacts in terms of emissions, water and land use.

Compare and contrast

If the paragraph makes a comparison or introduces contrasting information, the topic sentence can use words that highlight difference or conflict (for example, in contrast , however , yet , on the other hand ).

However , the environmental costs of dietary choices are not always clear-cut; in some cases, small-scale livestock farming is more sustainable than plant-based food production.

You can also imply contrast or complicate your argument by formulating the topic sentence as a question.

Is veganism the only solution, or are there more sustainable ways of producing meat and dairy?

Sometimes you can use a topic sentence to introduce several paragraphs at once.

All of the examples above address the environmental impact of meat-eating versus veganism. Together, they make up one coherent part of a larger argument, so the first paragraph could use a topic sentence to introduce the whole section.

In countries with high levels of meat consumption, a move towards plant-based diets is the most obvious route to making food more sustainable. Research has consistently shown that the meat industry has significant environmental impacts.

The topic sentence usually goes at the very start of a paragraph, but sometimes it can come later to indicate a change of direction in the paragraph’s argument.

Given this evidence of the meat industry’s impact on the planet, veganism seems like the only environmentally responsible option for consumers. However, the environmental costs of dietary choices are not always clear-cut; in some cases, small-scale livestock farming is more sustainable than plant-based food production.

In this example, the first sentence summarizes the main point that has been made so far. Then the topic sentence indicates that this paragraph will address evidence that complicates or contradicts that point.

In more advanced or creative forms of academic writing , you can play with the placement of topic sentences to build suspense and give your arguments more force. But if in doubt, to keep your research paper clear and focused, the easiest method is to place the topic sentence at the start of the paragraph.

View topic sentences in an example essay

A topic sentence is a sentence that expresses the main point of a paragraph . Everything else in the paragraph should relate to the topic sentence.

Topic sentences help keep your writing focused and guide the reader through your argument.

In an essay or paper , each paragraph should focus on a single idea. By stating the main idea in the topic sentence, you clarify what the paragraph is about for both yourself and your reader.

The topic sentence usually comes at the very start of the paragraph .

However, sometimes you might start with a transition sentence to summarize what was discussed in previous paragraphs, followed by the topic sentence that expresses the focus of the current paragraph.

Let’s say you’re writing a five-paragraph  essay about the environmental impacts of dietary choices. Here are three examples of topic sentences you could use for each of the three body paragraphs :

  • Research has shown that the meat industry has severe environmental impacts.
  • However, many plant-based foods are also produced in environmentally damaging ways.
  • It’s important to consider not only what type of diet we eat, but where our food comes from and how it is produced.

Each of these sentences expresses one main idea – by listing them in order, we can see the overall structure of the essay at a glance. Each paragraph will expand on the topic sentence with relevant detail, evidence, and arguments.

Elements of a Good Topic Sentence

Common pitfalls to avoid.

  • Where To Get Your Essay Edited For Free

Crafting the perfect essay takes time and dedication. There are so many elements you have to worry about, such as tone, purpose, and correct spelling and grammar. Writing a strong topic sentences is another critical part in writing a cohesive essay. 

Without a strong topic sentence, you risk losing your reader and perhaps part of your grade. If it’s a college admissions essay, then you need it to be as strong as possible to back up your application. Learn about what steps you should take to write a strong topic sentence.

What Is a Topic Sentence? 

People often confuse a topic sentence with a thesis statement. A thesis statement is typically at the end of your opening paragraph, that dictates the main argument you’ll be making in your essay. 

Throughout your essay, you’ll have multiple topic sentences, as each paragraph should start off with one. This beginning sentence is used to direct the topic of the paragraph and outline the flow of the following sentences. It’s used to help guide your reader and to continue to keep them hooked on your overall essay. Without topic sentences, your essay will be unorganized, lack transitions, and sound very choppy. To write a good topic sentence, there are several steps to take.

Writing a Good Topic Sentence: 5 Steps

Step 1: decide what you’re going to write about..

When you see the essay prompt, you’ll have some time to think through what you want to say and why. You have to decide if it’s a persuasive essay, informative, narrative, or descriptive. Determine your purpose for writing the essay after reading through the prompt. Whether it’s an assignment for school or if it’s to get into college, you need to make sure you have that purpose clearly outlined. 

Step 2: Create a thesis statement.

One of the first things you need to do is create a thesis statement. This is typically a sentence with three points that you’ll back up throughout your essay. 

For example: The Office became a cultural phenomenon because it spurred the careers of many of today’s successful movie stars, it talked about situations that most American workers can relate to, and even 15 years later, offers funny, relevant content that helps to break down prejudices. 

You then use that thesis statement to create an essay around the points you want to make. 

Step 3: Make your essay outline.

Once you have the points you want to make within your thesis statement hammered out, make an outline for your essay. This is where you’ll start to create your topic sentence for each paragraph. You want to clearly state the main idea of that paragraph in the very first sentence. From there, you back up that main idea with facts and reputable sources. Make sure your topic sentence is clear, but does not just announce your topic. 

For example, do not write something like: “In this paragraph, I will discuss why it’s bad that poachers are killing giraffes.”

Instead, write something that clearly states your idea with a reasonable opinion and that gives direction to the paragraph: “Giraffes are a key part of the African ecosystem, so it’s important to enforce regulations against the poachers who are killing them for their body parts.” 

You’d then follow that up with reasons why giraffes are a key part of the African ecosystem and how poachers are destroying their population.

Step 4: Begin writing your essay.

Once you have your thesis statement and you’ve created an outline with supporting paragraphs and their topic sentences, you can begin writing your essay. It’s important to make that outline before just jumping in–a disorganized essay can spell disaster for you as you continue to write, and could result in a poor grade. Many times, teachers will even require you to turn in your outline as part of your overall essay grade. 

Step 5: Proofread and check your resources.

After you’ve written the essay, go back through it with a fine tooth comb. Read through each topic sentence and the paragraphs that follow to ensure that you’ve written clear, solid topic sentences throughout and that the paragraphs with them make sense. During the proofreading phase, you also need to recheck the sources you’re using. Make sure each source is reputable. In other words, do not use sites like Wikipedia where anyone can go in and edit an article to add misinformation. Use sites that:

  • Are actual reputable news sources, such as the New York Times , CNN, CBS News
  • Have domain names that end in .edu or .gov
  • Come from an encyclopedia, such as Encyclopedia Britannica

Using sites that are not reputable could jeopardize the validity of your argument.

Our free chancing engine takes into account your history, background, test scores, and extracurricular activities to show you your real chances of admission—and how to improve them.

Now that you know the steps to set yourself up for success when writing a topic sentence, there are certain elements that go into a quality first sentence. Always make sure that your topic sentence is the first sentence of a paragraph. You don’t want to make your reader hunt for the point you’re trying to make. Check out some key elements of a good topic sentence:

Make sure your topic sentence isn’t too vague.

You need a topic sentence that has some specifics to it. It also needs to hook in your reader in some way with an opinion. A vague sentence makes it harder to write a paragraph that can clearly backs up your thoughts. For example:

DON’T: “In Pride and Prejudice, Mr. Bingley seems like a nice guy.”

DO: “When Mr. Bingley is first introduced, he comes across as a kind person because he speaks to everyone and doesn’t immediately pass judgment.”

Choose a reasonable opinion.

Your topic sentence should clearly outline whatever point you’re trying to make in the paragraph, but you want to pick a reasonable opinion that you can easily reinforce with facts and statistics. Here’s an example of what you should and should not do:

DON’T: “It’s obvious that Mr. Bingley was a total loser with no backbone.”

DO: “Mr. Bingley could have shown more confidence in his choices and stood up to Mr. Darcy when he found himself in love with Jane Bennet.”

You can then back that up with facts, saying that he was a wealthy Englishman and thus one of the key players in society at the time, which should have given him more confidence. If he’d been more confident, perhaps he would not have left and devastated Jane.

Use your topic sentence as a transition.

Along with telling the reader the point of your next paragraph, your topic sentence should also serve as a transition from the previous paragraph. Without a transition, the essay can feel like it’s choppy and disjointed. For example:

DON’T: “Mr. Bingley is a good man and here’s why.”

DO: “Although Mr. Bingley did break Jane’s heart by leaving, he ended up redeeming himself by returning to Netherfield Hall.”

Keep your topic sentence short.

A long, drawn-out topic sentence can risk losing your reader. Many times, it’s hard to determine the point of a sentence when it goes on for too long. You want a clear, concise sentence that draws in the reader but also leaves some room for you to expand on it in the following paragraph.

DON’T: “Throughout the novel of Pride and Prejudice, Mr. Bingley was often quite different from Mr. Darcy as he would treat all people in a friendly manner, considering them all his friends and acquaintances, even agreeing to throw a ball after Elizabeth’s sisters rudely demanded he do so and was gracious to Mr. and Mrs. Bennet as well despite their manners.”

DO: “Overall, Mr. Bingley served as a foil to Mr. Darcy throughout the story by treating everyone around him equally with dignity and grace.”

Writing an essay can be overwhelming at times, but so long as you avoid some of these common pitfalls, it can be easier to get it done on time. 

Don’t wait until the last minute.

If your teacher assigns you an essay or tells you that you have an essay test coming up, don’t wait until the day before to do anything about it. You have to plan or study and you need to give yourself time to do that. If you know it takes you a while to write something, then start planning it as soon as you get the assignment.

Don’t forget to write an outline.

Along with planning, make sure you have that outline written up and planned out well. It will serve as your guideline for writing the essay. Without it, you’ll face the risk of a disorganized essay that does not clearly illustrate your point.

Ask for help if you need it.

This may be the most important pitfall to avoid. If you get in over your head while writing, don’t be afraid to ask for help. Ask a friend to review the essay or ask your teacher for guidance.

How to Write a Topic Sentence (30+ Tips & Examples)

Writing the perfect topic sentence took me years to master.

After endless drafts, feedback sessions, and seeing what resonates with readers, I’ve distilled the ultimate guide to craft attention-grabbing, informative, and concise topic sentences.

Let’s dive into the essential tips for how to write a topic sentence.

What Is a Topic Sentence and Why Is It Important?

Bright lights spell 'TOPIC SENTENCES' above an awe-inspired crowd -- How to Write a Topic Sentence

Table of Contents

A topic sentence introduces the main idea, usually appearing at the start of a paragraph.

It sets the tone for the entire paragraph by giving a glimpse of what’s coming. Think of it as a headline for each paragraph that keeps your writing clear and focused.

A strong topic sentence is important because:

  • Grabs Attention: Captures the reader’s interest, encouraging them to keep reading.
  • Guides Structure: Helps organize thoughts in a logical way.
  • Provides Focus: Prevents rambling by clarifying the main point.

Types of Topic Sentences

Different types of topic sentences can fit various writing styles and purposes.

Understanding these types will help you select the best approach for your specific content.

  • Declarative Statements: These are straightforward sentences that make a clear assertion. They introduce the main idea without any fluff or ambiguity. Example: “Water conservation is critical in regions prone to drought.”
  • Interrogative Sentences: These topic sentences pose a question, encouraging readers to think critically and seek answers within the paragraph. Example: “How can sustainable practices help reduce waste in the fashion industry?”
  • Complex Sentences: By combining independent and dependent clauses, these topic sentences present a nuanced main idea that prepares readers for a more detailed discussion. Example: “Although renewable energy sources are gaining popularity, fossil fuels still dominate the global energy sector.”
  • Bridge Sentences: These link the preceding paragraph to the next, providing continuity and coherence in the overall structure. Example: “While electric vehicles offer a greener alternative to traditional cars, the infrastructure for widespread adoption remains lacking.”
  • Contrasting Statements: These topic sentences highlight opposing viewpoints or circumstances, building intrigue and depth into the following paragraph. Example: “Despite the technological advancements in healthcare, access remains limited for underserved communities.”

My 30 Best Tips for Writing a Topic Sentence

Now let’s get into the main section of this guide — where you will learn all the best tips for writing a compelling topic sentence on any subject.

Tip #1: State the Main Idea Clearly

Make sure your topic sentence introduces the primary idea succinctly.

Avoid vague language or cluttered wording. Your reader should immediately understand the topic.

  • Clear: “Recycling programs reduce landfill waste by promoting reusable packaging.”
  • Unclear: “Programs for recycling can be a good thing because it’s important.”

Tip #2: Keep It Simple and Direct

A topic sentence should be straightforward. Avoid complex structures and over-complicated phrasing.

Shorter sentences work best.

  • Simple: “Exercise improves mental health through endorphin production.”
  • Complicated: “One can expect to experience benefits in their mental state with exercise due to the generation of endorphins.”

Tip #3: Link to the Previous Paragraph

Create a smooth flow by connecting ideas to the paragraph before.

Transition words like “similarly,” “however,” or “in contrast” help show relationships.

  • Linked: “Similarly, the agricultural industry is also impacted by climate change.”
  • Disjointed: “Farmers are struggling with erratic weather patterns.”

Tip #4: Avoid Announcing Your Intentions

Steer clear of sentences like “In this paragraph, I will discuss…” They sound amateurish and reduce reader engagement.

  • Natural: “Effective communication skills are crucial for career advancement.”
  • Announcing: “This paragraph will explain why communication skills are important.”

Tip #5: Vary Sentence Structure

Using the same structure repeatedly can bore readers.

Mix up your approach by experimenting with different forms like questions, facts, and lists.

  • Varied: “How does cultural background influence consumer behavior?”
  • Repetitive: “Consumer behavior is influenced by cultural background.”

Tip #6: Be Specific, Not General

A vague topic sentence leaves the reader confused. Instead, provide specific information to establish clarity and interest.

  • Specific: “Remote work improves productivity by reducing commute times.”
  • General: “Remote work is beneficial for many reasons.”

Tip #7: Reflect Your Argument’s Tone

Match your topic sentence with the tone of your argument. For serious discussions, avoid informal language.

  • Formal: “The socioeconomic impact of urbanization requires comprehensive policy solutions.”
  • Informal: “The effects of city living need some fixing.”

Tip #8: Include a Controlling Idea

The controlling idea limits the scope of the paragraph, ensuring the reader knows what to expect next.

  • With Control: “Social media marketing increases brand visibility through targeted campaigns.”
  • Without Control: “Social media is important.”

Tip #9: Use Active Voice

Active voice is more engaging and dynamic. It also provides clarity.

  • Active: “New policies will reshape healthcare accessibility.”
  • Passive: “Healthcare accessibility will be reshaped by new policies.”

Tip #10: Make It Unique

Avoid using overused phrases or predictable statements. Offer a fresh perspective to captivate your reader.

  • Unique: “Biodegradable packaging is transforming the fast-food industry.”
  • Cliché: “The fast-food industry is changing with new trends.”

Tip #11: Create Curiosity

Tease your reader by leaving questions unanswered. Encourage them to keep reading for more.

  • Curious: “What are the unexpected benefits of rising inflation rates?”
  • Blunt: “Rising inflation rates have some positive effects.”

Tip #12: Support Your Thesis

Your topic sentence should align with your overall thesis. It will give your argument more coherence.

  • Aligned: “Reducing plastic waste aligns with our sustainability goals.”
  • Unaligned: “Plastic recycling is controversial.”

Tip #13: Focus on One Point

Don’t overwhelm readers with multiple ideas in one topic sentence. Stick to one clear concept.

  • One Point: “Artificial intelligence streamlines data analysis.”
  • Too Broad: “Artificial intelligence changes marketing, finance, and data analysis.”

Tip #14: Use Key Terms From the Prompt (if applicable)

If you are responding to an assignment or specific topic prompt, make sure your topic sentence directly incorporates relevant keywords.

  • Key Terms Included: “Global warming solutions must involve international cooperation.”
  • Lacks Terms: “Solutions for the environment require cooperation.”

Tip #15: Offer Context

Provide some context in the topic sentence to frame the discussion, giving the reader essential background information.

With Context: “As urbanization accelerates, city infrastructure struggles to keep up.” Without Context: “City infrastructure is lagging.”

Tip #16: Incorporate Comparisons

Comparisons can clarify complex concepts and give readers a familiar reference.

  • Comparison: “Just as the printing press revolutionized communication, the internet has transformed modern commerce.”
  • No Comparison: “The internet has transformed modern commerce.”

Tip #17: Present Solutions

Offering a solution at the start engages readers who are seeking actionable advice.

  • Solution: “Installing solar panels reduces energy bills while cutting carbon emissions.”
  • Problem-Only: “High energy bills are a widespread issue.”

Tip #18: Address Common Misconceptions

Challenge preconceived notions to spark curiosity and highlight the importance of your argument.

  • Challenging: “Despite common belief, vitamin supplements aren’t always beneficial.”
  • Reinforcing: “Vitamin supplements have benefits.”

Tip #19: Use Emotional Appeals

Appeal to the reader’s emotions to deepen their connection to your writing.

  • Emotional: “Volunteering at shelters uplifts communities and transforms lives.”
  • Neutral: “Volunteering at shelters is helpful.”

Tip #20: Avoid Redundancy

Ensure your topic sentence adds new value. Avoid repeating points covered elsewhere.

  • New Value: “Stronger copyright laws are crucial for protecting intellectual property.”
  • Redundant: “Intellectual property needs stronger protection.”

Tip #21: Ask a Thought-Provoking Question

Pose a question that makes the reader stop and think. This engages them immediately.

  • Provocative: “How will automation reshape the global workforce?”
  • Plain: “Automation is changing the global workforce.”

Tip #22: Include an Action Verb

Action verbs add momentum and urgency to your topic sentence. They make your point more dynamic.

  • Active Verb: “Investing in renewable energy fosters long-term economic growth.”
  • Lacks Action: “Renewable energy investments are beneficial.”

Tip #23: Paint a Picture

Use descriptive language to help readers visualize your point.

  • Descriptive: “Increased droughts have turned fertile farmlands into arid deserts.”
  • Bland: “Droughts are affecting farmlands.”

Tip #24: Use Parallel Structure

Parallel structure involves repeating similar grammatical forms.

It makes your writing rhythmic and easy to follow.

  • Parallel: “Tackling pollution requires reducing emissions, cleaning waterways, and limiting waste.”
  • Non-Parallel: “Tackling pollution requires emission reductions, waterways cleaning, and limiting waste.”

Tip #25: Emphasize Urgency

Highlight the time-sensitive nature of your argument to create urgency.

  • Urgent: “Immediate action is needed to prevent further deforestation.”
  • Calm: “Deforestation is a concern.”

Tip #26: Highlight Contrasts

Contrasting different ideas helps to emphasize your point and draw clear distinctions.

  • Contrast: “While technology creates new jobs, it also disrupts traditional industries.”
  • No Contrast: “Technology affects the job market.”

Tip #27: Lead with a Statistic

Start with a compelling number to catch the reader’s attention and back up your argument.

  • Statistic: “80% of small businesses struggle to comply with data privacy regulations.”
  • General Statement: “Small businesses struggle with data privacy.”

Tip #28: Build on Existing Knowledge

Assume the reader has some background knowledge and expand on it.

  • Builds On Knowledge: “With the rise of remote work, companies are rethinking their office spaces.”
  • Basic Information: “Remote work is changing office spaces.”

Tip #29: Start with an Anecdote

A brief anecdote adds a human touch, creating an immediate connection with the reader.

  • Anecdotal: “After years of burnout, Sarah switched to a part-time schedule to improve her work-life balance.”
  • Abstract: “Work-life balance is important.”

Tip #30: Use an Engaging Metaphor

A metaphor can illuminate your argument in an unexpected way.

  • Metaphor: “Effective teamwork is the glue that holds successful organizations together.”
  • Literal: “Effective teamwork is important for organizations.”

Anatomy of a Body Paragraph

TOPIC SENTENCE/ In his numerous writings, Marx critiques capitalism by identifying its flaws. ANALYSIS OF EVIDENCE/ By critiquing the political economy and capitalism, Marx implores his reader to think critically about their position in society and restores awareness in the proletariat class. EVIDENCE/ To Marx, capitalism is a system characterized by the “exploitation of the many by the few,” in which workers accept the exploitation of their labor and receive only harm of “alienation,” rather than true benefits ( MER 487). He writes that “labour produces for the rich wonderful things – but for the worker it produces privation. It produces palaces—but for the worker, hovels. It produces beauty—but for the worker, deformity” (MER 73). Marx argues capitalism is a system in which the laborer is repeatedly harmed and estranged from himself, his labor, and other people, while the owner of his labor – the capitalist – receives the benefits ( MER 74). And while industry progresses, the worker “sinks deeper and deeper below the conditions of existence of his own class” ( MER 483).  ANALYSIS OF EVIDENCE/ But while Marx critiques the political economy, he does not explicitly say “capitalism is wrong.” Rather, his close examination of the system makes its flaws obvious. Only once the working class realizes the flaws of the system, Marx believes, will they - must they - rise up against their bourgeois masters and achieve the necessary and inevitable communist revolution.

Not every paragraph will be structured exactly like this one, of course. But as you draft your own paragraphs, look for all three of these elements: topic sentence, evidence, and analysis.

Writing Topic Sentences — Purpose, Structure, and Examples

What is a topic sentence.

A topic sentence in academic writing identifies how a body paragraph relates to the overall purpose of an essay stated in the thesis statement . Topic sentences are usually at the beginning of a paragraph and identify the paragraph’s controlling idea.

While an essay’s thesis statement identifies the point of the essay in its entirety, the topic sentence has a much narrower focus, as it relates only to the paragraph in which it is located.

Topic sentence vs. thesis statement

What is the purpose of a topic sentence?

The purpose of a topic sentence is to inform the reader of the main idea of the paragraph and how it connects to the overall objective of the essay. An effective topic sentence accomplishes one or more of the following:

Makes a claim

Supports other claims made in the paper

Identifies the purpose of the rest of the paragraph

Relates the paragraph to the purpose of the paper

Precedes information that defends a claim

Purposes of a topic sentence

How to write a topic sentence

To write a topic sentence, incorporate the following guidelines:

Determine the thesis of the essay.

Identify the main supports that help prove the thesis.

Use each main support to structure a topic sentence for each paragraph.

Compose a sentence that answers the following questions:

What will the paragraph prove?

How does the paragraph connect to the thesis?

How to write a topic sentence

Where is the topic sentence in a paragraph?

Topic sentences can be placed at the beginning or end of a paragraph.

Although it does not need to be the first sentence, the topic sentence should be placed at the beginning of the paragraph so the reader can quickly identify the purpose of the paragraph.

While not a common placement for a topic sentence, some writers use topic sentences at the end of a paragraph. Writers who choose this method want the reader to deduce the main point of the paragraph by presenting the evidence first.

Topic sentence examples

The following list identifies topic sentences based on the provided thesis statements for five-paragraph essays:

Thesis Statement: Capital punishment should be banned because it is inhumane, unconstitutional, and ineffective at deterring crime.

Support Paragraph 1 Topic Sentence: The inhumane nature of the death penalty proves it should be abolished.

Support Paragraph 2 Topic Sentence: Capital punishment should be outlawed because it violates the Constitution.

Support Paragraph 3 Topic Sentence: Because the death penalty does not effectively deter criminal behavior, states should not continue to use it.

Thesis Statement: College athletes should be financially compensated because they sacrifice their minds and bodies, cannot hold an outside job, and increase the school’s revenue.

Support Paragraph 1 Topic Sentence: Student athletes should be paid for their performance because of sports’ impact on their minds and bodies.

Support Paragraph 2 Topic Sentence: Because most college athletes cannot play their sport and hold a job, colleges should give them a living wage.

Support Paragraph 3 Topic Sentence: Student-athletes’ ability to increase their college’s revenue proves they should be awarded financial compensation.

Example topic sentences

Thesis Statement: Using alternative energy sources can help lessen the impact of global climate change.

Support Paragraph 1 Topic Sentence: Through the widespread use of solar power, countries can limit the environmental impact of other energy sources.

Support Paragraph 2 Topic Sentence: Utilizing more wind turbines as a power source can help mitigate the effects of climate change.

Support Paragraph 3 Topic Sentence: Using geothermal power will effectively decrease the world's reliance on fossil fuels.

How to Write a Good Topic Sentence

Last Updated: June 26, 2024 Fact Checked

She earned her PhD in English from the University of Georgia in 2015. There are 10 references cited in this article, which can be found at the bottom of the page.

Perfecting the skill of writing topic sentences is essential to successful writing. A topic sentence usually comes at the beginning of a paragraph and lets your reader know what to expect from each paragraph. Think of it as the preview for a movie or a headline in a newspaper, highlighting the “main point” that’s to come in that paragraph. [1] X Research source Make sure your topic sentences are up to par, and the rest of your writing will feel like a breeze.

Writing a Successful Topic Sentence

Step 1 State your main idea clearly.

  • Keep in mind that this is not an invitation to simply announce your topic. “Today I’m going to discuss the benefits of gardening” is not an effective topic sentence. You should be able to make your intentions clear without stating them explicitly.
  • The topic sentence in this example states a clear direction (“health benefits of gardening”) that you can then elaborate on in your paragraph.

Step 2 Balance the topic sentence between specifics and general ideas.

  • Don’t write too vague or general an idea or you will never be able to discuss it in a single paragraph. This is too general: “The United States suffered a lot during the Civil War.”
  • Don’t write too narrow of a statement. There’s nothing much to talk about then, because it’s probably a fact. This is too narrow: “Christmas trees are either cedars or firs."
  • Instead, aim for a good balance: “Sherman’s destruction in the South during the Civil War also caused incredible suffering.” This is big enough to relate to the broader idea of an essay, but not so narrow that there’s nothing left to discuss.

Step 3 Hook your reader.

  • Describe a character. This can be a physical or emotional description.
  • Use dialogue. If there is a relevant conversation that will attract your reader’s attention, consider using part of it to start your paragraph.
  • Portray an emotion. Use the opening sentence to portray an emotion to your reader.
  • Use detail. While you don’t want to write a run on sentence by creating too much detail, it’s a good idea to create interest using sensory language in your topic sentence.
  • Avoid rhetorical questions. While you want your reader to formulate questions in his or her mind, you do not want to formulate the questions yourself.

Step 4 Keep it short and sweet.

  • Avoid presenting only facts in your topic sentence. While facts may be interesting, they do not introduce the reader to your paragraph nor do they draw the reader in. If you wish to include a fact, also include your own input. For example, instead of writing “All dogs need food,” try “All dogs need regular care, including healthy food, and children are the best ones to do it.” Alternatively, save your facts to use as evidence in the body of your paragraph.

Step 6 Use the topic sentence as a transition.

  • Using transitional elements, such as “In addition” or “In contrast,” is a good way to show the relationship between your ideas.
  • For example: “Although gardening has many health benefits, people still need to exercise caution when outside.” This topic sentence establishes a connection to the main idea of the previous paragraph (“health benefits of gardening”) and points to the direction of the new paragraph (“things to be cautious of”).

Planning Your Topic Sentences

Step 1  Write an...

  • You don’t have to write a formal outline using Roman numerals and the like. Even a loose, idea-based outline can help you know what you want to discuss.

Step 2 Understand the connection...

  • A topic sentence, unlike a thesis statement, doesn’t have to present an argument. It can present a “preview” of what the paragraph will argue or discuss.

Step 3 Look at some examples.

  • For example, a topic sentence could look like this: “In addition, increasing funding for public roads in Jackson County will improve local residents’ quality of life.” The rest of the sentences in this paragraph would relate to the main idea of public roads and how they will help benefit local residents.
  • This is not as successful a topic sentence: “Increased funding for public roads in Jackson County has decreased traffic by 20%.” While this is probably an interesting fact for your argument, it’s too narrow for a topic sentence. The topic sentence has to direct the whole paragraph.

Avoiding Common Problems

Step 1 Avoid introducing yourself.

  • Unless it is an opinion piece, avoid using ‘I’ in your topic sentences.

Step 2 Make sure your wording is clear.

  • Rather than stating something like “In the story, Amelia did many good things such as help out her friends, talk to her parents, and support her team at school” say something like “As a result of the many activities Amelia participated in, she was recognized for her positive influence on the community.”

Step 4 Avoid starting with a quote.

If you’re trying to write a good topic sentence, start by clearly stating your main idea, which should include the topic and the position you’re taking on it. Aim to write a sentence that’s broad enough for discussion but narrow enough to be covered in a single paragraph. If you can, start with a hook, like a detail, character, or emotion that would draw in your readers.

Paragraphs: Topic Sentences

Topic sentences video playlist.

Note that these videos were created while APA 6 was the style guide edition in use. There may be some examples of writing that have not been updated to APA 7 guidelines.

  • Academic Paragraphs: Introduction to Paragraphs and the MEAL Plan (video transcript)
  • Academic Paragraphs: Examples of the MEAL Plan (video transcript)

The best way to understand the role of the topic sentence in paragraph development is to imagine that any given paragraph is a miniature essay that has its own thesis, support, and conclusion. The parts of a paragraph easily correspond to the parts of an essay:

Thesis statement Topic sentence
Body paragraphs Supporting details, explanation, analysis
Conclusion Wrap-up sentence(s)

Just as an effective essay starts off with an introduction that presents the paper's thesis statement and indicates the specific claim or argument that the essay will develop, each paragraph should begin with a topic sentence that indicates the focus of that paragraph, alerting the reader to the particular subtopic that the paragraph will provide evidence to support.

A strong topic sentence should be placed at or near the beginning of a paragraph. In addition, this sentence should focus on a specific issue, avoid the use of direct quotations, and leave room for support and analysis within the body of the paragraph. Read on to learn more about creating an effective topic sentence.

The topic sentence does not have to be the first sentence in the paragraph; however, it should come early in the paragraph in order to orient the reader to the paragraph's focus right away. Occasionally a writer may place a transition sentence before the topic sentence, to create continuity between topics.

Topic Sentence to begin paragraph:

In the novel Sula , Morrison uses the physical bonds of female friendship to propel her characters into self-awareness.

Transition Sentence + Topic Sentence to begin paragraph:

However, Morrison does not only use the emotional and spiritual bonds between her female characters to initiate their coming-of-age. In addition, the author uses the physical bonds of female friendship to propel her adolescent protagonists into self-awareness.

Specificity

Your topic sentence should be more narrowly focused than your thesis sentence, and you will want to make sure the claim you are making can be supported, argued, and analyzed within the body of your paragraph.

Example: In the novel Sula , Morrison uses the physical bonds of female friendship to propel her characters into self-awareness.

In this topic sentence, the essayist is arguing that physical bonds of friendship, specifically, make the female characters more self-aware. Because this idea can be refuted or supported by readers (based on how successfully the essayist persuades his or her readers with examples and analysis from the novel), and because the claim is narrow enough to address within a single paragraph, the above sentence is a successful topic sentence.

Direct Quotations (Are Best Avoided)

Although it might be tempting to begin a paragraph with a compelling quotation, as a general rule, topic sentences should state the main idea of the paragraph in your own words. Direct quotations have a place later in the paragraph, where they may be incorporated to support the topic sentence.

Needs Improvement: As Morrison (1982) conveyed, the girls' "friendship let them use each other to grow on…they found in each other's eyes the intimacy they were looking for" (p. 52).
Better: In the novel Sula , Morrison uses the physical bonds of female friendship to propel her characters into self-awareness. Pointing to the connection of eyes meeting and bodies growing together, Morrison makes coming-of-age an interactive physical process between the adolescent protagonists. Specifically, Morrison describes how Sula and Nel have used "each other to grow on…they found in each other's eyes the intimacy they were looking for" (p. 52).

In this second paragraph, the topic sentence appears first, immediately orienting readers to the main focus (or topic) of the paragraph. The quotation is used later in the paragraph as a form of evidence or support for the topic sentence.

If you are finding it challenging to create effective topic sentences, you might consider outlining before beginning to write a paper. The points and subpoints of an outline can then become the topic sentences for the paper's paragraphs.

Additionally, because the topic sentence functions similarly at the paragraph level to the thesis at the essay level, you may also find it helpful to check out our thesis statement construction information. Our resource on paragraphs has helpful information about the scope of a paragraph, as well.

Paragraphs & topic sentences.

A paragraph is a series of sentences that are organized and coherent, and are all related to a single topic. Almost every piece of writing you do that is longer than a few sentences should be organized into paragraphs. This is because paragraphs show a reader where the subdivisions of an essay begin and end, and thus help the reader see the organization of the essay and grasp its main points.

Paragraphs can contain many different kinds of information. A paragraph could contain a series of brief examples or a single long illustration of a general point. It might describe a place, character, or process; narrate a series of events; compare or contrast two or more things; classify items into categories; or describe causes and effects. Regardless of the kind of information they contain, all paragraphs share certain characteristics. One of the most important of these is a topic sentence.

TOPIC SENTENCES

A well-organized paragraph supports or develops a single controlling idea, which is expressed in a sentence called the topic sentence. A topic sentence has several important functions: it substantiates or supports an essay’s thesis statement; it unifies the content of a paragraph and directs the order of the sentences; and it advises the reader of the subject to be discussed and how the paragraph will discuss it. Readers generally look to the first few sentences in a paragraph to determine the subject and perspective of the paragraph. That’s why it’s often best to put the topic sentence at the very beginning of the paragraph. In some cases, however, it’s more effective to place another sentence before the topic sentence—for example, a sentence linking the current paragraph to the previous one, or one providing background information.

Although most paragraphs should have a topic sentence, there are a few situations when a paragraph might not need a topic sentence. For example, you might be able to omit a topic sentence in a paragraph that narrates a series of events, if a paragraph continues developing an idea that you introduced (with a topic sentence) in the previous paragraph, or if all the sentences and details in a paragraph clearly refer—perhaps indirectly—to a main point. The vast majority of your paragraphs, however, should have a topic sentence.

PARAGRAPH STRUCTURE

Most paragraphs in an essay have a three-part structure—introduction, body, and conclusion. You can see this structure in paragraphs whether they are narrating, describing, comparing, contrasting, or analyzing information. Each part of the paragraph plays an important role in communicating your meaning to your reader.

Introduction : the first section of a paragraph; should include the topic sentence and any other sentences at the beginning of the paragraph that give background information or provide a transition.

Body : follows the introduction; discusses the controlling idea, using facts, arguments, analysis, examples, and other information.

Conclusion : the final section; summarizes the connections between the information discussed in the body of the paragraph and the paragraph’s controlling idea.

The following paragraph illustrates this pattern of organization. In this paragraph the topic sentence and concluding sentence (CAPITALIZED) both help the reader keep the paragraph’s main point in mind.

SCIENTISTS HAVE LEARNED TO SUPPLEMENT THE SENSE OF SIGHT IN NUMEROUS WAYS. In front of the tiny pupil of the eye they put , on Mount Palomar, a great monocle 200 inches in diameter, and with it see 2000 times farther into the depths of space. Or they look through a small pair of lenses arranged as a microscope into a drop of water or blood, and magnify by as much as 2000 diameters the living creatures there, many of which are among man’s most dangerous enemies. Or , if we want to see distant happenings on earth, they use some of the previously wasted electromagnetic waves to carry television images which they re-create as light by whipping tiny crystals on a screen with electrons in a vacuum. Or they can bring happenings of long ago and far away as colored motion pictures, by arranging silver atoms and color-absorbing molecules to force light waves into the patterns of original reality. Or if we want to see into the center of a steel casting or the chest of an injured child, they send the information on a beam of penetrating short-wave X rays, and then convert it back into images we can see on a screen or photograph. THUS ALMOST EVERY TYPE OF ELECTROMAGNETIC RADIATION YET DISCOVERED HAS BEEN USED TO EXTEND OUR SENSE OF SIGHT IN SOME WAY. George Harrison, “Faith and the Scientist”

In a coherent paragraph, each sentence relates clearly to the topic sentence or controlling idea, but there is more to coherence than this. If a paragraph is coherent, each sentence flows smoothly into the next without obvious shifts or jumps. A coherent paragraph also highlights the ties between old information and new information to make the structure of ideas or arguments clear to the reader.

Along with the smooth flow of sentences, a paragraph’s coherence may also be related to its length. If you have written a very long paragraph, one that fills a double-spaced typed page, for example, you should check it carefully to see if it should start a new paragraph where the original paragraph wanders from its controlling idea. On the other hand, if a paragraph is very short (only one or two sentences, perhaps), you may need to develop its controlling idea more thoroughly, or combine it with another paragraph.

A number of other techniques that you can use to establish coherence in paragraphs are described below.

Repeat key words or phrases. Particularly in paragraphs in which you define or identify an important idea or theory, be consistent in how you refer to it. This consistency and repetition will bind the paragraph together and help your reader understand your definition or description.

Create parallel structures. Parallel structures are created by constructing two or more phrases or sentences that have the same grammatical structure and use the same parts of speech. By creating parallel structures you make your sentences clearer and easier to read. In addition, repeating a pattern in a series of consecutive sentences helps your reader see the connections between ideas. In the paragraph above about scientists and the sense of sight, several sentences in the body of the paragraph have been constructed in a parallel way. The parallel structures (which have been emphasized ) help the reader see that the paragraph is organized as a set of examples of a general statement.

Be consistent in point of view, verb tense, and number. Consistency in point of view, verb tense, and number is a subtle but important aspect of coherence. If you shift from the more personal "you" to the impersonal “one,” from past to present tense, or from “a man” to “they,” for example, you make your paragraph less coherent. Such inconsistencies can also confuse your reader and make your argument more difficult to follow.

Use transition words or phrases between sentences and between paragraphs. Transitional expressions emphasize the relationships between ideas, so they help readers follow your train of thought or see connections that they might otherwise miss or misunderstand. The following paragraph shows how carefully chosen transitions (CAPITALIZED) lead the reader smoothly from the introduction to the conclusion of the paragraph.

I don’t wish to deny that the flattened, minuscule head of the large-bodied "stegosaurus" houses little brain from our subjective, top-heavy perspective, BUT I do wish to assert that we should not expect more of the beast. FIRST OF ALL, large animals have relatively smaller brains than related, small animals. The correlation of brain size with body size among kindred animals (all reptiles, all mammals, FOR EXAMPLE) is remarkably regular. AS we move from small to large animals, from mice to elephants or small lizards to Komodo dragons, brain size increases, BUT not so fast as body size. IN OTHER WORDS, bodies grow faster than brains, AND large animals have low ratios of brain weight to body weight. IN FACT, brains grow only about two-thirds as fast as bodies. SINCE we have no reason to believe that large animals are consistently stupider than their smaller relatives, we must conclude that large animals require relatively less brain to do as well as smaller animals. IF we do not recognize this relationship, we are likely to underestimate the mental power of very large animals, dinosaurs in particular. Stephen Jay Gould, “Were Dinosaurs Dumb?”

What is a Topic Sentence? (Definition, Examples, How to Use)

Topic sentence

What is a topic sentence ? A topic sentence , the first sentence of a paragraph, presents the main concept discussed in the paragraph. It must contain sufficient information to support numerous examples and subtopics without being too broad to obscure the essay’s intended purpose. The remaining sentences in the paragraph will act as supporting statements, providing evidence and examples for the main idea.

Topic sentence

Importance of topic sentences

In essays or articles , where subjects can shift from one paragraph to another, a topic phrase is particularly crucial. The topic sentences, superficially, may seem to serve the purpose of only acting like the initial or introductory sentence of a paragraph. But it has numerous other purposes that make it an important part of essays.

  • Topic sentences link paragraphs together to improve the sentence flow and make reading easier. When topic sentences are not used, switching between paragraphs can feel abrupt and jarring to the reader. Authors can maintain the rhythm of their writing using topic sentences and facilitate smooth transitions.
  • Topic sentences show the reader a sample of what to expect from the paragraph. The readers can determine from the topic sentence whether the paragraph will comprise a narrative, a list, anecdotal evidence, statistical data, persuasive opinions, or some other form of evidence.
  • If two conflicting viewpoints are presented in a single paragraph, authors can use more than one topic sentence to inform the readers about the changes in the main concept. For example, paragraphs that “compare and contrast” require more than one topic sentence. In these kinds of paragraphs, authors can start with a topic sentence introducing the first idea and follow it up with proof or evidence supporting the idea. Then they can introduce the second topic sentence conveying the opposing viewpoint, followed by proof or evidence supporting it.

Topic sentence

Different types of topic sentences

The different types of topic sentences include:

Simple statement

This topic sentence is used by authors to make a general observation or statement and then elaborate on it in the body of the paragraph.

New studies are emerging indicating the link between climate change and the emergence of numerous new virus strains.

Interrogative or question

This is used by writers in less formal settings. Authors can start a paragraph using implicit or explicit questions related to the topic of discussion to engage the readers.

How many nations are ready to adapt to rising sea levels?

Complex topic sentences are used when the author is discussing a complicated concept that encompasses multiple ideas. Such topic sentences cover more than a single core idea.

Although many people believe that a mother bird will reject its chick if it is touched by humans, the truth is that birds do not abandon their babies after humans touch them.

Authors can use their topic sentences to make explicit demands or pleas to their readers. This will be helpful in breaking the monotony of the essay.

Let’s look at the data from the latest research.

Purely transitional

Though topic sentences are generally responsible for facilitating a smooth transition between paragraphs, occasionally they are purely transitional. These function best when the main topic shifts abruptly by highlighting the switch.

But not everybody agrees.

Pivot sentences are not found at the beginning of a paragraph but rather in the middle, indicating a change in the topic. Conjunctive adverbs like however, furthermore, and meanwhile are frequently used with them.

However, the undisputed king of tennis, Roger Federer, was dethroned in 2008 at Wimbledon.

How to create good topic sentences

A good topic sentence can be created using some simple steps:

1. Determine the key point of your essay

Writers should first form an understanding of the topic of the essay and then create topic sentences to attract the attention of readers. Constructing a good thesis statement can assist the writer in forming better topic sentences.

2. Have an outline for the essay

The author should form a plan or roadmap beforehand on the topics they want to discuss in a paragraph and the evidence they want to use as supporting statements.

3. Be coherent and clear

Writers should make their topic sentences clear and comprehensible so that the reader can form a clear understanding of what to expect in the paragraph.

4. Share opinions

It is advisable to share the opinion or viewpoint of the author in the topic sentence to attract the attention of the reader. Authors should also refrain from writing obvious facts in the topic sentences.

5. Use specific wordings

The topic sentences ought to be precise enough so that the authors can use a few sentences in the paragraph to support them.

6. Transitions should be added between paragraphs

To give the essay or paper a throughline, authors can create topic sentences that refer to the prior paragraph. A topic sentence can make a reference to the preceding paragraph while introducing the next part by using transitional words.

7. Use new, relevant information

Instead of using an obvious fact that everybody knows as the topic sentence, authors can give new information. It is also important to present them in an interesting way.

8. Create a compound or complex topic statement

Compound or complex topic statements feel advanced and stronger. Authors can create such topic statements to add a high level of sophistication to their text.

Many beginner writers and students confuse thesis statements with topic sentences. In essence, thesis statements establish the major idea discussed in the entire essay or paper, as opposed to topic sentences, which introduce the central concept of a paragraph.

Both of these sentences are responsible for giving the readers a sample of what to expect, but in entirely different capacities. Suppose a person is writing a thesis about the different compounds present in coffee and the health benefits it offers.

The thesis statement will be a generalized statement indicating that there are numerous compounds in coffee that benefit the health of humans. But the topic sentence of each paragraph will introduce any single health benefit or compound present in the coffee.

Topic sentences are typically found at the beginning of a paragraph. But this does not mean that they cannot be placed elsewhere in the paragraph. In some cases, when the details discussed can be summarized into a general statement, topic sentences can be included at the end.

Similarly, in some paragraphs where multiple concepts are discussed, topic sentences may be used in the middle of the paragraph. The placement depends on the number of topics being discussed and the way they are discussed.

What is a topic sentence?

A topic sentence states the main point of a paragraph: it serves as a mini-thesis for the paragraph. You might think of it as a signpost for your readers—or a headline—something that alerts them to the most important, interpretive points in your essay. When read in sequence, your essay’s topic sentences will provide a sketch of the essay’s argument. Thus topics sentences help protect your readers from confusion by guiding them through the argument. But topic sentences can also help you to improve your essay by making it easier for you to recognize gaps or weaknesses in your argument.

Where do topic sentences go?

Topic sentences usually appear at the very beginning of paragraphs. In the following example from Anatomy of Criticism , Northrop Frye establishes the figure of the tragic hero as someone more than human, but less than divine. He backs up his claim with examples of characters from literature, religion and mythology whose tragic stature is a function of their ability to mediate between their fellow human beings and a power that transcends the merely human:

The tragic hero is typically on top of the wheel of fortune, half-way between human society on the ground and the something greater in the sky. Prometheus, Adam, and Christ hang between heaven and earth, between a world of paradisal freedom and a world of bondage. Tragic heroes are so much the highest points in their human landscape that they seem the inevitable conductors of the power about them, great trees more likely to be struck by lightning than a clump of grass. Conductors may of course be instruments as well as victims of the divine lightning: Milton’s Samson destroys the Philistine temple with himself, and Hamlet nearly exterminates the Danish court in his own fall.

The structure of Frye’s paragraph is simple yet powerful: the topic sentence makes an abstract point, and the rest of the paragraph elaborates on that point using concrete examples as evidence.

Does a topic sentence have to be at the beginning of a paragraph?

No, though this is usually the most logical place for it. Sometimes a transitional sentence or two will come before a topic sentence:

We found in comedy that the term bomolochos or buffoon need not be restricted to farce, but could be extended to cover comic characters who are primarily entertainers, with the function of increasing or focusing the comic mood. The corresponding contrasting type is the suppliant, the character, often female, who presents a picture of unmitigated helplessness and destitution. Such a figure is pathetic, and pathos, though it seems a gentler and more relaxed mood than tragedy, is even more terrifying. Its basis is the exclusion of an individual from the group; hence it attacks the deepest fear in ourselves that we possess—a fear much deeper than the relatively cosy and sociable bogey of hell. In the suppliant pity and terror are brought to the highest possible pitch of intensity, and the awful consequences of rejecting the suppliant for all concerned is a central theme of Greek tragedy.

The context for this passage is an extended discussion of the characteristics of tragedy. In this paragraph, Frye begins by drawing a parallel between the figure of the buffoon in comedy and that of the suppliant in tragedy. His discussion of the buffoon occurred in a earlier section of the chapter, a section devoted to comedy. The first sentence of the current paragraph is transitional: it prepares the way for the topic sentence. The delayed topic sentence contributes to the coherence of Frye’s discussion by drawing an explicit connection between key ideas in the book. In essays, the connection is usually between the last paragraph and the current one.

Sometimes writers save a topic sentence for the end of a paragraph. You may, for example, occasionally find that giving away your point at the beginning of a paragraph does not allow you to build your argument toward an effective climax.

How do I come up with a topic sentence? And what makes a good one?

Ask yourself what’s going on in your paragraph. Why have you chosen to include the information you have? Why is the paragraph important in the context of your argument? What point are you trying to make?

Relating your topic sentences to your thesis can help strengthen the coherence of your essay. If you include a thesis statement in your introduction, then think of incorporating a keyword from that statement into the topic sentence. But you need not be overly explicit when you echo the thesis statement. Better to be subtle rather than heavy-handed. Do not forget that your topic sentence should do more than just establish a connection between your paragraph and your thesis. Use a topic sentence to show how your paragraph contributes to the development of your argument by moving it that one extra step forward. If your topic sentence merely restates your thesis, then either your paragraph is redundant or your topic sentence needs to be reformulated. If several of your topic sentences restate your thesis, even if they do so in different words, then your essay is probably repetitive.

Does every paragraph need one?

No, but most do. Sometimes a paragraph helps to develop the same point as in the previous paragraph, and so a new topic sentence would be redundant. And sometimes the evidence in your paragraph makes your point so effectively that your topic sentence can remain implicit. But if you are in doubt, it’s best to use one.

Topic Sentences

What is a topic sentence.

  • A statement at the beginning of each body paragraph
  • Indicates the topic of the entire paragraph
  • In a short essay, it reflects one of the main points of the thesis statement (link to thesis statement handout)

Main Point + Details

An effective topic sentence expands on a main thesis point by including details and explanation. It has two organizational purposes:

  • Relate back to the thesis statement
  • Summarize the paragraph

An effective topic sentence is like a mini-thesis statement for each paragraph.

Example Thesis: Health-conscious individuals should consider substituting strawberries for desserts because strawberries are healthy , sweet , and versatile .   Topic of Body Paragraph 1: Strawberries are healthy   Topic of Body Paragraph 2: Strawberries are sweet   Topic of Body Paragraph 3: Strawberries are versatile

Topic Sentence for Body Paragraph 1: Strawberries are a healthy substitute for desserts because they have a much lower carbohydrate count and are rich in nutrients and fiber.  

Notice that the topic sentence includes the first main point of the thesis statement, but it expands on the idea with further details. Now the paragraph can elaborate further on these details, and it should relate back to the main argument – that strawberries can be substituted for desserts.

The second body paragraph would start with a topic sentence about the second main point: strawberries are sweet . The third body paragraph would start with a topic sentence about the third main point: strawberries are versatile .

Longer Essays

Not all papers will have a three point thesis statement. If this is the case, the topic sentence may not contain a word-for-word point stated in the thesis statement.

Example Thesis statement: The literary techniques used by Leo Tolstoy in The Death of Ivan Ilych unveil an extraordinary sense of depth within the novella that is imperative to truly understanding Tolstoy’s ideas.

Example Topic Sentence: When Leo Tolstoy employs the technique of symbolism, inanimate objects like Ivan’s golden pocket watch and the drapes on his windows convey hidden meanings that further clarify important themes in the story.

Topic Sentences for Body Paragraphs: Examples and Explanation

An essay with the first sentence highlighted and the words

A key to becoming a better writer is learning how to cover one main idea in each paragraph and write clearly—topic sentences can help you do that by focusing your writing.

Let’s look at what a topic sentence is, how to write a good topic sentence, and topic sentence examples.

What is a topic sentence in a paragraph?

A topic sentence is a sentence that introduces the main idea of the paragraph—it tells the reader what the paragraph is about in a clear and concise manner. It organizes an essay, engages the reader, provides a focus for the paragraph, and relates each paragraph back to the thesis.

A topic sentence is generally the first sentence in your body paragraph or at least at the beginning of the paragraph.

Topic sentences provide structure and organization to your essay—this is helpful for both the writer and the reader.

You have to build on your topic sentence. You make your claim in the topic sentence, which serves as a base to add your supporting details, evidence, and examples that strengthen your argument.

The purpose of a topic sentence is to provide a clear focus for your paragraph and preview what you will discuss in the paragraph.

Is the topic sentence always the first sentence?

The topic sentence is usually at the beginning to help the reader understand what the paragraph is about. However, a topic sentence can be in the middle or end of the paragraph (though this would be rare for body paragraphs).

Can a topic sentence be more than one sentence?

A topic sentence is traditionally one sentence—this is recommended to state your point clearly and concisely. However, a topic sentence can be 2 or 3 sentences long if you are explaining the claim.

If you decide you must make your topic sentence longer to express your main idea, make sure to edit and try to remain as concise as possible. Also, do not overly use multiple topic sentences, as this can make your essay lack focus or structure.

Topic sentences for paragraphs that are not a part of an essay

What is a good topic sentence.

A good topic sentence is clear and concise. It is general enough to cover what the entire paragraph is about but specific enough to make it easy to understand the main idea of what will be discussed. It should relate back to the thesis or question and help maintain the flow of the essay.

How to write a topic sentence for a body paragraph

Effective strategies for writing a topic sentence include that you pivot between ideas, make sure that you express the topic and what you will talk about in the paragraph, and use transition words—such as although, another example/way/argument, even though, in addition to, likewise, therefore, or however.

Make sure you then expand on the statement and give supporting details and reasons, examples, or sources.

Topic sentences for body paragraphs examples

Let’s look at topic sentences that illustrate your point that you will expand on, provide transitions, compare and contrast topics, show cause and effect relationships, express counterclaims that you will proceed to address, or answer a question.

Example 1: Stating your claim

These could look like:

If I only talk about the benefits of learning a new language on your memory, I would make my topic sentence more specific—”Learning a new language can improve a person’s memory.”

Example 2: Transitions

If your writing an opinion essay about why dogs make the best pets, and your previous paragraph said that they are good companions because they are loyal, your next paragraph could start with the topic sentence: “Another reason why dogs are good companions is that they are affectionate.”

Example 3: Compare and contrast topics

For example: “While in-person classes offer better social interactions, online classes offer more flexibility.”

Example 4: Show cause and effect relationship

Example 5: introduce a counterclaim.

A topic sentence can also introduce a counterclaim.

Example 6: Answering a question

Let’s look at an example of a topic sentence that answers a question.

You can also answer a question in a topic sentence in an essay if you end the previous paragraph with a question.

Now that you know how to write a topic sentence and have seen topic sentences for body paragraphs examples, you are well on your way to becoming a better writer.

30 Topic Sentence Examples

June 24, 2024

What is an essay without a topic sentence? Well, confusion. In your writing, the topic sentence introduces what the paragraph will be about. It should cover the topic of the paragraph and the prime focus of what you want to discuss in the next several lines. And it can assist in smoothly transitioning into the next paragraph, the next point you’re about to make. Depending on the complexity of your argument, the topic sentence can also weave together several paragraphs. So when the topic sentence is missing, it’s easy to lose track of what your specific message is. Below, you find 30 topic sentence examples.

Think of the topic sentence as a tool in your writing kit. It’s there to help you signpost and structure the argument of your essay. Having it, while making sure the topic is interesting and clear, is essential to help your reader truly understand your thesis.

How do you write a topic sentence?

When you’re about to write an essay, you won’t find yourself immediately thinking of every topic sentence example at once. Figuring out what your thesis is going to be, the very purpose and argument of your essay, will be a necessary first step . Then you might want to create an outline . The outline can draft out what you want to cover in each paragraph or how your argument will be supported.

This is where the topic sentence comes in. For every paragraph, you can begin to think of topic sentence examples that best sum up the rest of your idea. The more interesting you can make the topic sentence, the better it will be, so long as you can support it. Remember, the topic sentence will introduce what you are going to discuss and expand on in the rest of the paragraph.

Examples (Continued)

Let’s take a look at these six topic sentence examples below that introduce a paragraph:

1) Studies over the last ten years have shown that the use of social media has a significant role in teenage mental health.

2) Kate Jackson and her family, who have all been San Francisco residents for 30 years, noted that this was the hottest summer yet.

3) Book sales across the country have actually increased this year, contrary to popular belief.

4) During COVID-19, people rushed to adopt pets, but after the pandemic ended many of those pets were surrendered to shelters.

5) It is undeniable what impact the meat industry has had on our environment.

6) In the 19th century in France, the creation of the Braille system was a significant turning point for those with disabilities.

How do you imagine the rest of the paragraph will turn out? How can you best support your topic sentence to strengthen your overall essay?

Support your paragraph with evidence

The topic sentence of your paragraph will not hold well if it is not backed up with the right evidence. After writing a topic sentence like the topic sentence examples above, the rest of your paragraph should include strong examples of evidence to support your argument. Doing so will only help validate your topic sentence and allow your reader to have more insight into your thesis.

Considering each topic sentence examples above, try to think of what types of evidence you would expect in that same paragraph. There could be reports on statistics, interviews, and other forms of evidence provided. How will yours be?

Where should the topic sentence go?

Now you know that your topic sentence should be followed by the right evidence. So it’s safe to assume that the topic sentence belongs at the very beginning of the paragraph.

Yet depending on the paragraph you’re working on, you can also place your “main” topic sentence after an “intro” topic sentence. Let’s take a look at the two examples below:

7) Due to rising temperatures around the world, people have had to flee their homes and relocate to areas less prone to fires or floods. (Intro topic sentence)

8) However, many have found that even these “safer” locations are still susceptible to eventual natural disasters. (Main topic sentence)

When we combine the two sentences, we get:

Due to rising temperatures around the world, people have had to flee their homes and relocate to areas less prone to fires or floods. However, many have found that even these “safer” locations are still susceptible to eventual natural disasters.

The first (intro) topic sentence example is more generic and introductory, functioning like a summary of an observation. The second (main) topic sentence example then presents another contradictory argument to that first point. Depending on the tone or argument you want to make in your paragraph, you can format your topic sentences in such a way to further sharpen your thesis. Whenever you have doubt though, you can always place one topic sentence at the beginning of the paragraph.

Sometimes less is more in writing the topic sentence

The topic sentence introduces the key concept of that paragraph, along with evidence and research findings. It can even be written as more than one sentence or perspective, as noted directly above. However, you also don’t want to say too much. Why?

You don’t want to give all of your information away at once. While it is imperative to write a clear, specific, and even complex topic sentence, it’s just as important to avoid being too general or too informative. Striking the right balance is going to help you structure the rest of your essay. After all, you have the rest of the paragraph and the rest of your essay to do that, which leads us to our next point.

Topic sentences for smoother transitions

Like a game of dominoes, your paragraphs are all connected and should flow smoothly into the next statement you are making. As you are building your outline, or even as you’re already writing, consider how your previous paragraph transitions into the next . This depends on the intention of each paragraph and how you are structuring your argument.

Topic sentences for paragraph transitions have many functions. They will elaborate on more examples. They can wrap up or summarize a preceding point you made, providing another perspective. Also, they can go against a fact or opinion you wrote, which is a great way to strengthen your overall thesis and they can also be posed as a question.

Take a look at these transitional topic sentence examples below:

9) In fact, walking as a form of exercise has shown to reduce cortisol levels.

10) Furthermore, city council representatives have said that environmental sustainability has remained at the top of the agenda, but activists have largely disagreed.

11) While the strike in Hollywood has come to an end, many writers are still without employment and searching for new ways to restart their careers.

12) However, grocery prices across the country still seem to have risen.

13) Despite the state’s discontinued funding for the arts, is there another feasible way for these students to gather together and flourish as young artists at their school?

More than one paragraph: Topic sentences that expand into several key points

So far we’ve covered topic sentences that elaborate on just one paragraph. However, you might find that one topic sentence (or two) can best address several paragraphs. This usually occurs when you’re trying to introduce a bigger argument to serve your essay.

Let’s take one of the single paragraph topic sentences from earlier above and expand it by adding a connecting topic sentence to it:

14)Book sales across the country have actually increased this year, contrary to popular belief.

15) A report from the Association of American Publishers’ StatShot program states that in April sales over a year there has been an 18% increase.

These two topic sentence examples can even serve as their own introductory paragraph. This can then lead into more paragraphs related to the topic of specific book sales increasing across the country:

Book sales across the country have actually increased this year, contrary to popular belief. A report from the Association of American Publishers’ StatShot program states that in April sales over a year there has been an 18% increase.

Make the topic sentence interesting, not obvious

Check out 15 more topic sentence examples below. How do they introduce the topic, and what does it make you want to learn more about? You can imagine what kind of paragraph, or paragraphs, might follow afterwards:

16) When brewed correctly, coffee can hold strong, subtle hints of flavors such as chocolate or fruit, depending on the level of acidity.

17) Although today life in 1920s Paris is often romanticized for its glamor, jazz, and fashion, the city was still struggling to recover from the devastation of World War I.

18) Strict social rules dominated the Victorian Era, despite Britain’s expansion around the world in pursuit of wealth and power.

19) Dogs have a keen sense of time, so much so that they can predict when you’re late to take them out for a walk.

20) Before winter arrives, birds such as cranes and waterfowl follow preferred aerial pathways during their yearly migrations.

21) Conservation methods have helped local farms in their efforts to prioritize sustainability.

22) Did you know that humans would have a better chance of reaching Mars if they had a base set up on the moon?

23) The Pacific Ocean covers more than 30 percent of the earth’s surface, and it is home to so many life forms that have not yet been studied.

24) It is often debated whether or not student athletes should be paid for their performance, considering the cost for them to succeed.

25) Becoming a successful CEO doesn’t just happen overnight.

26) Although purchasing a home is considered a great form of investment, potential buyers should look at the real estate market first.

27) Watching my mother work three jobs to support our family has taught me the importance of resilience and strong work ethic.

28) Historical fiction not only has the power to teach us of actual past events. It also allows us to step into the lives of those we would have never met.

29) Parents and teachers at Sunnyroad School District are advocating for schools to provide free computers for their students – but the administrators aren’t so sure.

30) Across the country, the debate around whether teenagers should be allowed to use smart phones on campus has been circulating.

The topic sentence as a guide

One way to look at topic sentences is to imagine them as guiding compasses of your essay. Whatever point you are trying to make, the topic sentence has the power to guide your reader down a certain path. Choose wisely!

A topic sentence is the first sentence of a paragraph in an essay that introduces the main idea or topic of that paragraph. It serves as a roadmap for the reader, letting them know what to expect in the upcoming paragraph. 

Purpose of Topic Sentence

The purpose of a topic sentence is to clearly and concisely convey the main point of the paragraph to the reader. 

It helps to guide the reader through the essay, making it easier for them to follow the overall argument or narrative.

Types of Topic Sentences

There are several different types of topic sentences that can be used in writing to introduce the reader through a paragraph or essay.

Simple Statement Topic Sentence This is the most common type of topic sentence, which straightforwardly states the main point or idea of the paragraph or essay.

Example: The rise of social media has revolutionized the way people communicate with each other.

Complex Topic Sentence This type of topic sentence is more nuanced and may require some explanation or elaboration to fully understand.

Example: While the rise of social media has had many positive effects on communication, it has also led to concerns about privacy and online harassment.

Pivot Topic Sentence A pivot topic sentence begins by connecting the current paragraph or idea to the previous one, before pivoting to introduce a new point or idea.

Example: Building on the idea of social media's impact on communication, it is important to consider how it has also affected business and marketing strategies.

Question Topic Sentence A question topic sentence poses a question that the rest of the paragraph or essay will answer or explore.

Example: How has social media changed the way businesses interact with customers and advertise their products?

Command Topic Sentence This type of topic sentence gives a directive or instruction, often used in persuasive or argumentative essays.

Example: Support local businesses by shopping at independently owned stores instead of large chains.

How to Write a Topic Sentence?

Here are a few instructions to help you write a good topic sentence. 

Step#1 Clearly State The Main Idea

A topic sentence is the first paragraph of the paragraph. It must clearly explain the particular subject that would be discussed in the paragraph. This should be stated in very clear language so that the reader can easily understand the idea. 

Also, it should include a bit of your personal opinion and also the main idea. 

Step#2 Hook Your Reader

Grab your reader's attention with an intriguing topic sentence. It would excite and make the reader curious about the content and convince them to read the particular part. 

Look out for some amazing hook examples and see what fits your essay type. 

Use a meaningful and relevant question or a fact as a topic sentence of the paragraph. Make sure that you have identified your audience and are developing everything accordingly. 

Step#3 Keep It Short and Precise

The paragraph topic sentence must be expressive enough that a reader understands your point of view effortlessly. This is only possible if you keep everything to the point, short, and meaningful. 

Choose the words in such a way that they help you express your idea in an ideal way. Avoid using complex sentences and use independent clauses.  

A topic sentence acts as a link between a paragraph and the main thesis statement. It should be specific and connected to the overall essay. Keeping it short and precise helps maintain the paragraph's flow and its relevance to the rest of the writing.

Step#4 Give A Reasonable Opinion

The body paragraph explains a topic sentence. This is why it is important that you should write this sentence in such a way that it can be explained in the paragraph.  If you are mentioning a fact in the topic statement, make sure that you have authentic evidence to support it. 

While the topic sentence is an integral part of the paragraph, it should stand out and possess a distinctiveness that sets it apart from the other sentences. This can be achieved by employing transition words and establishing connections between sentences.

Step#5 Use The Topic Sentence As A Transition

The topic sentences that serve as transition sentences can be considered a guide for the readers. This way, they can help the reader to move through the essay in a flow. 

Write this sentence in such a way that it creates a gateway between the previous paragraph and the rest of the essay. Moreover, it will also help keep the essay organized, and the reader understands the point of a paragraph.

Step#6 Look For Some Good Examples

Examples can help you learn a thing in a better way. If you are new to writing topic sentences, it can help to look at some examples. Find some great examples of topic sentences relevant to your essay topic.

Difference Between Topic Sentence and Thesis Sentence

Here's a table outlining the differences between a topic sentence and a thesis statement:

A sentence that introduces the main idea or topic of a paragraphA statement that presents the main argument or claim of an essay or research paper

Typically found at the beginning of a paragraphTypically found at the end of an introduction

Limited to one paragraphSpans the entire essay or research paper

Introduces the main idea of a paragraph and connects it to the thesis statementPresents the main argument or claim of an essay and provides a roadmap for the reader

Helps to organize the content of the paragraph and keeps the writer focused on the main pointHelps to organize the content of the entire essay or research paper and guides the reader through the argument

Good Topic Sentence Examples

Here are ten examples of good topic sentences:

  •  "Despite the advancements in technology, traditional forms of communication are still essential in today's society."
  • "The theme of power is prevalent throughout Shakespeare's play, Macbeth."
  • "In recent years, there has been a growing concern over the impact of climate change on our planet."
  • "The legalization of marijuana has been a topic of debate for many years." "Education is the key to success in life."
  • "The rise of social media has greatly impacted the way we communicate with one another."
  • "The effects of childhood trauma can have a lasting impact on mental health."
  • "The concept of justice is explored in depth in Harper Lee's To Kill a Mockingbird."
  • "Eating a balanced diet is crucial for maintaining good health."
  • "The Industrial Revolution had a profound effect on the world as we know it today."

The Bottom Line!

An opening sentence is crucial to grab your reader's attention and set the tone for your piece of writing. The topic sentence introduces the controlling idea and acts as an important sentence in the essay outline. 

Effective topic sentences are necessary for a well-structured and organized essay. It's an integral part of the writing process that should not be overlooked. 

Make sure to spend time crafting a compelling topic sentence that clearly conveys your main point and guides your readers throughout your essay. You can even take ideas from an AI essay generator to get started.

Topic Sentence

Every paragraph should include a topic sentence that identifies the main idea of the paragraph. A topic sentence also states the point the writer wishes to make about that subject. Generally, the topic sentence appears at the beginning of the paragraph. It is often the paragraph’s very first sentence. A paragraph’s topic sentence must be general enough to express the paragraph’s overall subject. However, it should be specific enough that the reader can understand the paragraph’s main subject and point.

  • The topic sentence should identify the main idea and point of the paragraph. To choose an appropriate topic sentence, read the paragraph and think about its main idea and point.
  • The supporting details in the paragraph (the sentences other than the topic sentence) will develop or explain the topic sentence. Read all the supporting details in the paragraph and think about the ideas they discuss.
  • The topic sentence should not be too general or too specific. When considering the options, look for a topic sentence that is general enough to show the paragraph’s main idea instead of just one of its details. The answer should be specific enough that the reader understands the main idea of the paragraph.

More About the Topic Sentence

A topic sentence is the most important sentence in a paragraph. Sometimes referred to as a focus sentence, the topic sentence helps organize the paragraph by summarizing the information in the paragraph. In academic writing, the topic sentence is usually the first sentence in a paragraph (although it does not have to be).

Purpose of the Topic Sentence

A topic sentence essentially tells readers about the rest of the paragraph. All sentences after it have to give more information about that sentence, prove it by offering facts about it, or describe it in more detail. For example, if the topic sentence concerns the types of endangered species that live in the ocean, then every sentence after that needs to expands on that subject.

Topic sentences also need to relate back to the thesis of the essay. The thesis statement is like a road map that will tell the reader or listener where you are going with this information or how you are treating it.

Topic Sentences and Controlling Ideas

Every topic sentence will have a topic and a controlling idea. The controlling idea shows the direction the paragraph will take.

Examples of a Topic Sentence

Topic Sentence: There are many reasons why pollution in ABC Town is the worst in the world.

The topic is "pollution in ABC Town is the worst in the world" and the controlling idea is "many reasons."

Topic Sentence: To be an effective CEO requires certain characteristics.

The topic is "To be an effective CEO" and the controlling idea is "certain characteristics."

Topic Sentence: There are many possible contributing factors to global warming.

The topic is "global warming" and the controlling idea is "contributing factors."

Topic Sentence: Fortune hunters encounter many difficulties when exploring a shipwreck.

The topic is "exploring a shipwreck" and the controlling idea is "many difficulties."

Topic Sentence: Dogs make wonderful pets because they help you to live longer.

The topic is "dogs make wonderful pets" and the controlling idea is "because they help you

to live longer."

Topic Sentence: Crime in poverty-stricken areas occurs because of a systemic discrimination.

The topic is "crime in poverty stricken areas" and the controlling idea is "systemic discrimination."

Topic Sentence: Teen pregnancy may be prevented by improved education.

The topic is "teen pregnancy may be prevented" and the controlling idea is "improved education."

Topic Sentence: Cooking requires a number of different skills.

The topic is "cooking" and the controlling idea is "many different skills."

Topic Sentence: It is important to be ready before buying a house.

The topic is "buying a house" and the controlling idea is “it is important to be ready."

Topic Sentence: Graduating from high school is important for many different reasons.

The topic is "graduating from high school" and the controlling idea is "many different reasons."

Topic Sentence: Having a first child is difficult because of the significant adjustments in your life.

The topic is "having a first child" and the controlling idea is "significant adjustments in your life."

Topic Sentence: Remodeling a kitchen successfully requires research and a good eye.

The topic is "remodeling a kitchen" and the controlling idea is "requires research and a good eye."

Topic Sentences

Characteristics of a strong topic sentence.

decorative image

The topic sentence functions two ways: it clearly refers to and supports the essay’s thesis, and it indicates what will follow in the rest of the paragraph. As the unifying sentence for the paragraph, it is the most general sentence, whereas all supporting sentences provide different types of more specific information, such as facts, details, or examples. An effective topic sentence has the following characteristics:

  • A topic sentence has a topic and an angle, extracted from the thesis sentence.

Thesis : Although working for the national parks service may be considered by some to be a “summer job,” careers with the national parks offer mobility within the profession, support for continued learning, and satisfaction in knowing that you are contributing to the preservation and health of the country’s resources.

Weak example #1 : National Parks in the U.S. were created in 1916 under President Woodrow Wilson and currently offer hundreds of summer job opportunities per year.

Explanation : This sentence sticks with the topic, national parks, but does not offer an angle extracted from the ideas in the thesis. An essay should not have topic sentences and units of support that are not planned for in the thesis.

Stronger example : Workers with the national parks are encouraged and, in many cases, required to maintain current knowledge within their fields, which is offered through on-the-job training, attendance at seminars, and tuition assistance for appropriate college courses.

Explanation : Choose any part of the angle in the thesis to create a topic sentence with its own topic and angle.

Weak example #2 : National Parks work has provided me with many benefits.

Explanation : Although the thesis itself deals with benefits, a topic sentence derived from that thesis needs to more carefully extract a specific portion of that that thesis and make a point about that specific portion.

  • A topic sentence provides an accurate indication of what will follow in the rest of the paragraph.

Weak example : First, we need a better way to educate students.

Explanation : The claim is vague because it does not provide enough information about what will follow, and it is too broad to be covered effectively in one paragraph or short unit of support.

Stronger example : Creating a national set of standards for math and English education will improve student learning in many states.

Explanation : The sentence replaces the vague phrase “a better way” and leads readers to expect supporting facts and examples as to why standardizing education in these subjects might improve student learning in many states.

  • A good topic sentence is the most general sentence in the paragraph and thus does not include supporting details.

Weak example : Salaries should be capped in baseball for many reasons, most importantly so we don’t allow the same team to win year after year.

Explanation : This topic sentence includes a supporting detail that should be included later in the paragraph to back up the main point.

Stronger example : Introducing a salary cap would improve the game of baseball for many reasons.

Explanation : This topic sentence omits the additional supporting detail so that it can be expanded upon later in the paragraph, yet the sentence still makes a claim about salary caps – improvement of the game.

  • A good topic sentence is clear and easy to follow.

Weak example : In general, writing an essay, thesis, or other academic or nonacademic document is considerably easier and of much higher quality if you first construct an outline, of which there are many different types.

Explanation : The confusing sentence structure and unnecessary vocabulary bury the main idea, making it difficult for the reader to follow the topic sentence.

Stronger example : Most forms of writing can be improved by first creating an outline.

Explanation : This topic sentence cuts out unnecessary verbiage and simplifies the previous statement, making it easier for the reader to follow. The writer can include examples of what kinds of writing can benefit from outlining in the supporting sentences.

How to Write a Topic Sentence? (Examples & Tips)

A topic sentence is an  important component of every well-structured paragraph . It introduces the main idea and sets the tone for the rest of the paragraph that follows.

Additionally, it is mandatory to structure introductory and supporting paragraphs for every kind of nonfiction writing, including ; essays, theses, blogs, articles, etc. So, perfecting the skill of writing strong topic sentences can be helpful to uplift your writing to the next level.

In this comprehensive blog post, we’re going to discuss useful tips and examples for writing a topic sentence.

What is a Topic Sentence?

A topic sentence refers to the first sentence of a paragraph that reflects its main points . The purpose of this sentence is to tell the readers about what information they are going to read in the rest of the paragraph. It usually comes at the start of a paragraph, though it can also be placed elsewhere.

A topic sentence is also known as;

  • Introductory sentence.
  • Focus sentence.
  • Opening sentence.

This introductory/topic sentence tells the readers that the paragraph is about the health benefits of doing regular exercise.

Tips to Write a Strong Topic Sentence

Here are some useful tips to help you craft compelling topic/introductory sentences;

1. Determine the Main Idea

As aforementioned a topic sentence is solely focused on the main idea or key point of the paragraph. So, before you begin to write the focus sentence, there’s a need to identify the main idea first.

Useful Tips:

Below are some tips to help you determine the main idea of a paragraph;

  • You should brainstorm the key points of a paragraph for which you’re going to craft the opening sentence. To do so, it would be helpful to jot down all the key details.
  • Now, we suggest creating an outline to logically organize these points.
  • Finally, narrow down to the specific idea that you think could enclose the essence of your paragraph.

, the focus/main idea might be that .

2. Start With a Hook

Let’s make your topic sentence compelling. For this, the next tip is to begin the opening sentence with a hook. By hook , we refer to the compelling/interesting statement that grabs the attention of readers.

Types of Hooks that You Can Include in A Topic Sentence:

Some commonly used hook types are lisG

ed below with examples for each;

  • A hook line can be a surprising fact or impressive data , like; "Did you know that just 6 minutes of reading a day can cut your stress levels by up to 68%?”
  • You can use a stimulating question as a hook statement, such as; " How can a simple , regular practice elevate your creative writing to the next level?”
  • You can address a solved mystery in the hook line; for example; “ What ultimately convinced the senator to change their mind?”
  • Also, you can use an anecdote or quote in the hook line, for instance; " Author Stephen King once said, 'Books are a uniquely portable magic.'"

3 . Write Something New and Interesting

Include something interesting and attention-grabbing in the introductory sentence. Avoid using statements that are obvious that everyone knows. So, to craft a topic sentence, write information in a new and unique way.

Tip: Avoid casual and unnecessary words or phrases, but you are required to use compelling, interesting, powerful, and trendy terms to draw readers in.

4. Balance Between Specific & General

Ensure that your main sentence strikes a good balance between the specific/narrow and the general/broad. Don’t write the topic sentence around too broad or vague an idea that is impossible to cover in a single paragraph.

 

Similarly, you shouldn’t write a too narrow statement that has nothing much to say in the supporting sentences.

Instead , you should maintain a good balance and write an idea that is neither too generic nor too specific. Below is an example of such a topic sentence;

✔️ “Incorporating technology into classroom learning can enhance student engagement and understanding without overwhelming traditional teaching methods.”

Pro Tip: Also, choose a particular writing style/tone of your paragraph in the sentence; Persuasive, Informative, Descriptive, Formal, etc . You should choose this according to the overall writing style of your content.

5. Write Concise and Clear

Another effective tip that can help you write a good topic sentence is to use concise and clear wording. You should write a sentence that is succinct and to the point. Also, it should convey the main idea clearly without any jargon, complexity, or unnecessary details.

All in all, you should aim for brevity and maintain a smooth flow in your paragraph.

For Examples:

Error-free and Innovative Way to Write a Topic Sentence

Topic Sentence: Definition, Examples and Useful Tips for Writing A Topic Sentence

When writing, there are many aspects which we need to take into consideration. One such aspect is the topic sentence, but how do we use this? In this article, we are looking at what the topic sentence is and how it is used within a piece of writing . We are also going to be looking at a variety of examples to give us a better understanding of its function.

Topic Sentence

What is a topic sentence.

Some might say that the topic sentence is one of the most important aspects and definitely the most vital sentence within a paragraph . In some cases, you might hear the topic sentence is referred to as the focus sentence but these are essentially the same thing.

A topic sentence is used to summarise all of the information within a paragraph. When writing in a more formal style, the topic sentence will usually feature at the beginning of the paragraph, although this is not a set rule.

What Is A Topic Sentence Used For?

A writer will use a topic sentence as a way of explaining to the audience what the paragraph is going to be about. Any sentences which appear after the topic sentence should give further information about the topic sentence or should give facts about it in order to prove the claim that it has made. The following sentences might also serve as a way to further describe the topic sentence by giving more details about it. For example, if the topic sentence is about animals kept as domestic pets, the following sentences should relate back to that subject.

On top of this, the topic sentence should always refer back to the thesis statement which was made at the beginning of the essay . You can imagine the thesis statement as being a map which directs the reader as to where you are going with the information and how it is being treated.

Controlling Ideas

When writing a topic sentence, each one should feature a controlling idea. This will serve as an indicator as to where the rest of the paragraph will go and what will be discussed.

Topic Sentences Examples

Now that we are clear on what a topic sentence is, we are going to take a look at some examples to further grow our understanding of them.

  • ‘There are a lot of reasons why (name of a city) is the most polluted in the world.’

The controlling topic here is that there are ‘a lot of reasons’ and the topic is that a certain town is the most polluted.

  • ‘In order to be an effective manager, one must have certain qualities.’

The topic of this sentence is being an effective manager and it has a controlling idea of ‘certain qualities.’

  • ‘There are a lot of factors which contribute to global warming .’

This sentence has a topic of global warming whilst the controlling idea is related to ‘factors which contribute.’

  • ‘We can improve teen pregnancy rates by improving education.’

The topic of this sentence in that teen pregnancy can be improved and the controlling idea is ‘improving education.’

How To Write A Topic Sentence

When it comes to writing a good topic sentence, there are many things that you should take into consideration before you put pen to paper. We are now going to look at the various steps you should take in order to write an effective and strong topic sentence.

Write Your Thesis Statement

Before you can write a topic sentence, you must have a thesis statement. This should be strong and be effective in summing up the purpose of the essay as well as the main argument.

Outline Your Essay And Draft Out The Topic Sentences

The next step is to create your essay outline, this will give your essay structure and will allow you to detail what is going to be discussed in each paragraph. You will also make note of what data and evidence will be included in each of the paragraphs.

This is the point where you can play with words and draft up some topic sentences for each of your paragraphs. A topic sentence needs to be much more specific than your thesis statement but it should relate clearly to it.

Expand With Some Evidence

The remaining sentences within your paragraph should logically flow from the original topic sentence. They should be used to expand on what has been said in the topic sentence. This will not only make your workflow but will also ensure that each paragraph remains focused and relevant to the topic sentence. You should give some evidence to support your topic sentence.

Revise The Topic Sentences

What your topic sentence looks like to begin with may not be how it ends up in the final draft and that is OK. It is very important that you look over and edit each topic sentence within the essay as you go along. This will ensure that they remain relevant to the content of your paragraphs.

When making the final edits for your topic sentences, you should ensure that they are clear enough to allow the reader to know what the paragraph is going to be about but also not so clear that they detail everything you wish to talk about within that paragraph.

Transitions

Your topic sentence will sometimes serve as a transition between your paragraphs and in this case, they may do one of the following things:

  • Compare and contrast
  • Emphasise or expand

A topic sentence is one which appears, usually (but not always) at the beginning of each paragraph of an essay. The topic sentence is used to layout the ideas and arguments that will be covered within the paragraph and should be carefully planned out to ensure that they are clear enough to give the reader an idea of what will be discussed but not to give away too much about the content of the paragraph. Your topic sentence may serve one of many purposes including summarising and comparing.

What Is a Topic Sentence?

A topic sentence is the first sentence of a paragraph that conveys the general concept or theme of the work.

It includes enough information to support numerous subtopics and examples but doesn't obscure the purpose of the text. A strong topic sentence is brief , powerful , and emphasizes critical thought with supporting information.

  • The positioning of the topic sentence varies depending on the author's intentions. Starting with the topic sentence guides readers to the key message immediately.
  • When significant details lead to a generalization, it is sensible to place the topic sentence at the end of the paragraph.

The Purpose of a Topic Sentence

A topic sentence's purpose is to direct the reader to the subject of the paragraph . It presents the particular issue of the text section and relates to the essay's thesis statement . Moreover, topic sentences structure an essay by dividing it into key points.

Topic Sentence Vs. Thesis

Although the topic and thesis statements should be precise, concise, and explicit, they differ:

Topic Sentence Thesis Statement


✍️ How to Write a Body Paragraph Topic Sentence

There are four practical steps you have to take to create a solid topic sentence .

Determine the main idea of the paragraph . To write a topic sentence, you must understand the subject matter of your paper. A thesis statement will help you identify the fundamental concept of the paragraph.

Create a statement . Creating a statement that includes what and why questions and leads to your core idea is essential. You must describe the issue and explain why it is crucial.

Formulate the topic sentence . Write a statement that introduces the subtopic of a particular paragraph and leads readers back to the thesis statement. You can keep using the what and why structure as you write new topic sentences for each section.

Add transitions between paragraphs . Topic sentences should also establish a throughline in your research paper by drawing on the previous sections. Utilize transition words to refer to the previous paragraph while heading to the next section.

A topic sentence consists of 2 parts:

  • The topic . This is the paragraph's subject, indicating what the paragraph is about.
  • The controlling idea. This is the point that leads to the supporting arguments and limits its scope.

Here are some examples from our topic sentence generator with the topics in bold and the controlling ideas in italic .

  • Strength . The topic sentence should provide explicit and unambiguous information.
