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.

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.

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?
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.”
