The goal of a thesis statement is to let your reader know what your paper or essay is about. It helps your reader understand the greater context and scope of your topic, plus it lets your readers know what to expect from the rest of the work.
A secondary benefit of a thesis statement is that it makes it easier to search for papers on a particular topic, especially in the realm of academic writing like research papers and thesis papers (which are sometimes known as dissertations when written for doctoral degrees). For example, if you’re writing a paper of your own, you’ll want to look up other papers to use as evidence and sources . You can simply scan the thesis statements of several papers to see which match your topic and could be worthwhile sources to cite.
Before we get into details, here are the basic steps for how to write a thesis statement:
- Develop the best topic to cover in your paper
- Phrase your topic as a question-and-answer
- Add some polish
We ’ ll describe each of those steps in more detail below, but we wanted to share a quick guide. Also, we ’ ll provide some thesis statement examples and talk about how to write a thesis statement for different kinds of essays: persuasive, compare-and-contrast, expository, and argumentative essays.
The thesis statement is located at the beginning of a paper, in the opening paragraph, making it an essential way to start an essay . A thesis statement isn’t necessarily the first sentence in an essay; typically you’ll want to hook the reader in an engaging way in the opening sentence before inserting your central idea or argument later in the first paragraph. A thesis statement is often confused with a topic sentence , the first sentence in a paragraph, because they both introduce the central idea of what follows. You can think of thesis statements as the topic sentence of your entire paper.
Thesis statements are a necessary part of paper and essay writing , but different formats have different rules and best practices. Below, we break down how to write a thesis statement for the most common types of papers.
How to write a thesis statement for expository and argumentative essays
Expository and argumentative essays are some of the most common types of academic papers. Because they don’t have a formal abstract like research papers, they rely on their thesis statements to provide an overview of what’s discussed.
Thesis statements for argumentative and expository essays should use strong and decisive language; don’t be wishy-washy or uncertain. You want to take a stand right in the opening so that your readers understand what your paper is trying to show.
Moreover, thesis statements for these essays should be specific, with some minor details to hint at the rest of the paper. It’s not enough to merely make your point; you also want to provide some basic evidence or background context to paint a full picture.
If your paper dives into different subtopics or categories, try to fit them into the thesis statement if you can. You don’t have to get into details here, but it’s nice to mention the different sections at the top so that the reader knows what to expect.
Thesis statement examples
Despite the taboo, insects make an excellent food source and could stem humanity’s looming food shortage, based on both their protein output and the sustainability of farming them.
The backlash to rock ’n’ roll music in the ’50s by religious groups and traditionalists actually boosted the genre’s popularity instead of diminishing it as intended.
How to write a thesis statement for persuasive essays
Similar to argumentative essays, persuasive essays follow many of the same guidelines for their thesis statements: decisive language, specific details, and mentions of subtopics.
However, the main difference is that, while the thesis statements for argumentative and expository essays state facts, the thesis statements for persuasive essays state clear opinions . Still, the format is the same, and the opinions are often treated like facts, including conclusive language and citing evidence to support your claims.
Furthermore, unlike with other essays, it’s appropriate to make emotional connections in a thesis statement in persuasive essays. This can actually be a clever strategy to start your essay off on a more personal, impactful note.
Advertising should not be allowed in public schools because it’s a distraction from studies and may lead to misguided priorities among the school board, to say nothing of the materialist culture it promotes.
Exotic pets provide the same love and companionship as conventional pets, so the laws regulating which animals can and cannot be kept as pets should be more relaxed.
How to write a thesis statement for compare-and-contrast essays
Thesis statements for compare-and-contrast essays are tricky because you have at least two topics to touch on instead of just one. The same general guidelines apply (decisive language, details, etc.), but you need to give equal attention to both your topics—otherwise, your essay will seem biased from the start.
As always, your thesis statement should reflect what’s written in the rest of your essay. If your essay spends more time comparing than contrasting, your thesis statement should focus more on similarities than differences.
It sometimes helps to give specific examples as well, but keep them simple and brief. Save the finer details for the body of your essay.
Sean Connery and Daniel Craig are the two most popular actors to portray James Bond, but both have their own distinct and at times contradictory interpretations of the character.
Now that you know what you’re aiming for, it’s time to sit down and write your own thesis statement. To keep you on track, here are three easy steps to guide you.
1 Brainstorm the best topic for your essay
You can’t write a thesis statement until you know what your paper is about, so your first step is choosing a topic.
If the topic is already assigned, great ! That’s all for this step. If not, consider the tips below for choosing the topic that’s best for you:
- Pick a topic that you’re passionate about. Even if you don’t know much about it, it’ll be easier to learn about it while writing if you’re genuinely interested.
- Narrow down your topic to something specific; otherwise, your paper will be too broad and perhaps too long. Just make sure it’s not too specific, or you won’t have enough to write about. Try to find a happy medium.
- Check beforehand that there are enough strong, credible sources to use for research. You don’t want to run out of referential material halfway through.
Once you’ve chosen a topic—and the angle or stance you want to take—then it’s time to put the idea for your thesis sentence into words.
2 Phrase your topic as a question and then answer it
It’s not always easy to fit your entire thesis into just one sentence, let alone one that’s written clearly and eloquently. Here’s a quick technique to help you get started.
First, phrase your topic as a question. For example, if you want to write about Mahatma Gandhi’s legacy, ask yourself, “What influences did Gandhi have on society after his death?”
If you already know the answer, write it down—that’s a good start for your thesis statement. If you don’t know the answer, do some preliminary research to find out; you can certainly use what you discover as evidence and sources in your essay’s body paragraphs .
3 Add some polish
Chances are, your first attempt at a thesis statement won’t be perfect. To get it to its best, try revising , editing , and adding what’s missing.
Remember the core traits for thesis statements we mentioned above: decisive language, a happy medium of specific but not too specific details, and mention of subtopics. If you’re struggling to contain everything in a single sentence, feel free to move the secondary information to the following sentence. The thesis statement itself should only have what’s most necessary.
If you’re in doubt, read your thesis statement to a friend and ask them what they think your paper is about. If they answer correctly, your thesis statement does its job.
Next comes the hard part—writing the rest! While the bulk of the writing lies ahead, at least you’ve nailed down your central idea. To plot out your supporting argument, follow our advice on essay structure and let your ideas flow.

Tips for Writing Your Thesis Statement
1. Determine what kind of paper you are writing:
- An analytical paper breaks down an issue or an idea into its component parts, evaluates the issue or idea, and presents this breakdown and evaluation to the audience.
- An expository (explanatory) paper explains something to the audience.
- An argumentative paper makes a claim about a topic and justifies this claim with specific evidence. The claim could be an opinion, a policy proposal, an evaluation, a cause-and-effect statement, or an interpretation. The goal of the argumentative paper is to convince the audience that the claim is true based on the evidence provided.
If you are writing a text that does not fall under these three categories (e.g., a narrative), a thesis statement somewhere in the first paragraph could still be helpful to your reader.
2. Your thesis statement should be specific—it should cover only what you will discuss in your paper and should be supported with specific evidence.
3. The thesis statement usually appears at the end of the first paragraph of a paper.
4. Your topic may change as you write, so you may need to revise your thesis statement to reflect exactly what you have discussed in the paper.
Thesis Statement Examples
Example of an analytical thesis statement:
The paper that follows should:
- Explain the analysis of the college admission process
- Explain the challenge facing admissions counselors
Example of an expository (explanatory) thesis statement:
- Explain how students spend their time studying, attending class, and socializing with peers
Example of an argumentative thesis statement:
- Present an argument and give evidence to support the claim that students should pursue community projects before entering college
Developing a Thesis Statement
Many papers you write require developing a thesis statement. In this section you’ll learn what a thesis statement is and how to write one.
Keep in mind that not all papers require thesis statements . If in doubt, please consult your instructor for assistance.
What is a thesis statement?
A thesis statement . . .
- Makes an argumentative assertion about a topic; it states the conclusions that you have reached about your topic.
- Makes a promise to the reader about the scope, purpose, and direction of your paper.
- Is focused and specific enough to be “proven” within the boundaries of your paper.
- Is generally located near the end of the introduction ; sometimes, in a long paper, the thesis will be expressed in several sentences or in an entire paragraph.
- Identifies the relationships between the pieces of evidence that you are using to support your argument.
Not all papers require thesis statements! Ask your instructor if you’re in doubt whether you need one.
Identify a topic
Your topic is the subject about which you will write. Your assignment may suggest several ways of looking at a topic; or it may name a fairly general concept that you will explore or analyze in your paper.
Consider what your assignment asks you to do
Inform yourself about your topic, focus on one aspect of your topic, ask yourself whether your topic is worthy of your efforts, generate a topic from an assignment.
Below are some possible topics based on sample assignments.
Sample assignment 1
Analyze Spain’s neutrality in World War II.
Identified topic
Franco’s role in the diplomatic relationships between the Allies and the Axis
This topic avoids generalities such as “Spain” and “World War II,” addressing instead on Franco’s role (a specific aspect of “Spain”) and the diplomatic relations between the Allies and Axis (a specific aspect of World War II).
Sample assignment 2
Analyze one of Homer’s epic similes in the Iliad.
The relationship between the portrayal of warfare and the epic simile about Simoisius at 4.547-64.
This topic focuses on a single simile and relates it to a single aspect of the Iliad ( warfare being a major theme in that work).
Developing a Thesis Statement–Additional information
Your assignment may suggest several ways of looking at a topic, or it may name a fairly general concept that you will explore or analyze in your paper. You’ll want to read your assignment carefully, looking for key terms that you can use to focus your topic.
Sample assignment: Analyze Spain’s neutrality in World War II Key terms: analyze, Spain’s neutrality, World War II
After you’ve identified the key words in your topic, the next step is to read about them in several sources, or generate as much information as possible through an analysis of your topic. Obviously, the more material or knowledge you have, the more possibilities will be available for a strong argument. For the sample assignment above, you’ll want to look at books and articles on World War II in general, and Spain’s neutrality in particular.
As you consider your options, you must decide to focus on one aspect of your topic. This means that you cannot include everything you’ve learned about your topic, nor should you go off in several directions. If you end up covering too many different aspects of a topic, your paper will sprawl and be unconvincing in its argument, and it most likely will not fulfull the assignment requirements.
For the sample assignment above, both Spain’s neutrality and World War II are topics far too broad to explore in a paper. You may instead decide to focus on Franco’s role in the diplomatic relationships between the Allies and the Axis , which narrows down what aspects of Spain’s neutrality and World War II you want to discuss, as well as establishes a specific link between those two aspects.
Before you go too far, however, ask yourself whether your topic is worthy of your efforts. Try to avoid topics that already have too much written about them (i.e., “eating disorders and body image among adolescent women”) or that simply are not important (i.e. “why I like ice cream”). These topics may lead to a thesis that is either dry fact or a weird claim that cannot be supported. A good thesis falls somewhere between the two extremes. To arrive at this point, ask yourself what is new, interesting, contestable, or controversial about your topic.
As you work on your thesis, remember to keep the rest of your paper in mind at all times . Sometimes your thesis needs to evolve as you develop new insights, find new evidence, or take a different approach to your topic.
Derive a main point from topic
Once you have a topic, you will have to decide what the main point of your paper will be. This point, the “controlling idea,” becomes the core of your argument (thesis statement) and it is the unifying idea to which you will relate all your sub-theses. You can then turn this “controlling idea” into a purpose statement about what you intend to do in your paper.
Look for patterns in your evidence
Compose a purpose statement.
Consult the examples below for suggestions on how to look for patterns in your evidence and construct a purpose statement.
- Franco first tried to negotiate with the Axis
- Franco turned to the Allies when he couldn’t get some concessions that he wanted from the Axis
Possible conclusion:
Spain’s neutrality in WWII occurred for an entirely personal reason: Franco’s desire to preserve his own (and Spain’s) power.
Purpose statement
This paper will analyze Franco’s diplomacy during World War II to see how it contributed to Spain’s neutrality.
- The simile compares Simoisius to a tree, which is a peaceful, natural image.
- The tree in the simile is chopped down to make wheels for a chariot, which is an object used in warfare.
At first, the simile seems to take the reader away from the world of warfare, but we end up back in that world by the end.
This paper will analyze the way the simile about Simoisius at 4.547-64 moves in and out of the world of warfare.
Derive purpose statement from topic
To find out what your “controlling idea” is, you have to examine and evaluate your evidence . As you consider your evidence, you may notice patterns emerging, data repeated in more than one source, or facts that favor one view more than another. These patterns or data may then lead you to some conclusions about your topic and suggest that you can successfully argue for one idea better than another.
For instance, you might find out that Franco first tried to negotiate with the Axis, but when he couldn’t get some concessions that he wanted from them, he turned to the Allies. As you read more about Franco’s decisions, you may conclude that Spain’s neutrality in WWII occurred for an entirely personal reason: his desire to preserve his own (and Spain’s) power. Based on this conclusion, you can then write a trial thesis statement to help you decide what material belongs in your paper.
Sometimes you won’t be able to find a focus or identify your “spin” or specific argument immediately. Like some writers, you might begin with a purpose statement just to get yourself going. A purpose statement is one or more sentences that announce your topic and indicate the structure of the paper but do not state the conclusions you have drawn . Thus, you might begin with something like this:
- This paper will look at modern language to see if it reflects male dominance or female oppression.
- I plan to analyze anger and derision in offensive language to see if they represent a challenge of society’s authority.
At some point, you can turn a purpose statement into a thesis statement. As you think and write about your topic, you can restrict, clarify, and refine your argument, crafting your thesis statement to reflect your thinking.
As you work on your thesis, remember to keep the rest of your paper in mind at all times. Sometimes your thesis needs to evolve as you develop new insights, find new evidence, or take a different approach to your topic.
Compose a draft thesis statement
If you are writing a paper that will have an argumentative thesis and are having trouble getting started, the techniques in the table below may help you develop a temporary or “working” thesis statement.
Begin with a purpose statement that you will later turn into a thesis statement.
Assignment: Discuss the history of the Reform Party and explain its influence on the 1990 presidential and Congressional election.
Purpose Statement: This paper briefly sketches the history of the grassroots, conservative, Perot-led Reform Party and analyzes how it influenced the economic and social ideologies of the two mainstream parties.
Question-to-Assertion
If your assignment asks a specific question(s), turn the question(s) into an assertion and give reasons why it is true or reasons for your opinion.
Assignment : What do Aylmer and Rappaccini have to be proud of? Why aren’t they satisfied with these things? How does pride, as demonstrated in “The Birthmark” and “Rappaccini’s Daughter,” lead to unexpected problems?
Beginning thesis statement: Alymer and Rappaccinni are proud of their great knowledge; however, they are also very greedy and are driven to use their knowledge to alter some aspect of nature as a test of their ability. Evil results when they try to “play God.”
Write a sentence that summarizes the main idea of the essay you plan to write.
Main idea: The reason some toys succeed in the market is that they appeal to the consumers’ sense of the ridiculous and their basic desire to laugh at themselves.
Make a list of the ideas that you want to include; consider the ideas and try to group them.
- nature = peaceful
- war matériel = violent (competes with 1?)
- need for time and space to mourn the dead
- war is inescapable (competes with 3?)
Use a formula to arrive at a working thesis statement (you will revise this later).
- although most readers of _______ have argued that _______, closer examination shows that _______.
- _______ uses _______ and _____ to prove that ________.
- phenomenon x is a result of the combination of __________, __________, and _________.
What to keep in mind as you draft an initial thesis statement
Beginning statements obtained through the methods illustrated above can serve as a framework for planning or drafting your paper, but remember they’re not yet the specific, argumentative thesis you want for the final version of your paper. In fact, in its first stages, a thesis statement usually is ill-formed or rough and serves only as a planning tool.
As you write, you may discover evidence that does not fit your temporary or “working” thesis. Or you may reach deeper insights about your topic as you do more research, and you will find that your thesis statement has to be more complicated to match the evidence that you want to use.
You must be willing to reject or omit some evidence in order to keep your paper cohesive and your reader focused. Or you may have to revise your thesis to match the evidence and insights that you want to discuss. Read your draft carefully, noting the conclusions you have drawn and the major ideas which support or prove those conclusions. These will be the elements of your final thesis statement.
Sometimes you will not be able to identify these elements in your early drafts, but as you consider how your argument is developing and how your evidence supports your main idea, ask yourself, “ What is the main point that I want to prove/discuss? ” and “ How will I convince the reader that this is true? ” When you can answer these questions, then you can begin to refine the thesis statement.
Refine and polish the thesis statement
To get to your final thesis, you’ll need to refine your draft thesis so that it’s specific and arguable.
- Ask if your draft thesis addresses the assignment
- Question each part of your draft thesis
- Clarify vague phrases and assertions
- Investigate alternatives to your draft thesis
Consult the example below for suggestions on how to refine your draft thesis statement.
Sample Assignment
Choose an activity and define it as a symbol of American culture. Your essay should cause the reader to think critically about the society which produces and enjoys that activity.
- Ask The phenomenon of drive-in facilities is an interesting symbol of american culture, and these facilities demonstrate significant characteristics of our society.This statement does not fulfill the assignment because it does not require the reader to think critically about society.
Drive-ins are an interesting symbol of American culture because they represent Americans’ significant creativity and business ingenuity.
Among the types of drive-in facilities familiar during the twentieth century, drive-in movie theaters best represent American creativity, not merely because they were the forerunner of later drive-ins and drive-throughs, but because of their impact on our culture: they changed our relationship to the automobile, changed the way people experienced movies, and changed movie-going into a family activity.
While drive-in facilities such as those at fast-food establishments, banks, pharmacies, and dry cleaners symbolize America’s economic ingenuity, they also have affected our personal standards.
While drive-in facilities such as those at fast- food restaurants, banks, pharmacies, and dry cleaners symbolize (1) Americans’ business ingenuity, they also have contributed (2) to an increasing homogenization of our culture, (3) a willingness to depersonalize relationships with others, and (4) a tendency to sacrifice quality for convenience.
This statement is now specific and fulfills all parts of the assignment. This version, like any good thesis, is not self-evident; its points, 1-4, will have to be proven with evidence in the body of the paper. The numbers in this statement indicate the order in which the points will be presented. Depending on the length of the paper, there could be one paragraph for each numbered item or there could be blocks of paragraph for even pages for each one.
Complete the final thesis statement
The bottom line.
As you move through the process of crafting a thesis, you’ll need to remember four things:
- Context matters! Think about your course materials and lectures. Try to relate your thesis to the ideas your instructor is discussing.
- As you go through the process described in this section, always keep your assignment in mind . You will be more successful when your thesis (and paper) responds to the assignment than if it argues a semi-related idea.
- Your thesis statement should be precise, focused, and contestable ; it should predict the sub-theses or blocks of information that you will use to prove your argument.
- Make sure that you keep the rest of your paper in mind at all times. Change your thesis as your paper evolves, because you do not want your thesis to promise more than your paper actually delivers.
In the beginning, the thesis statement was a tool to help you sharpen your focus, limit material and establish the paper’s purpose. When your paper is finished, however, the thesis statement becomes a tool for your reader. It tells the reader what you have learned about your topic and what evidence led you to your conclusion. It keeps the reader on track–well able to understand and appreciate your argument.
