What is a thesis statement?
A thesis statement is one or two sentences that state the main point of your essay. It usually comes at the end of your introduction and tells the reader what you will argue or explain, so every paragraph that follows has a job to do.
A good thesis statement is specific, arguable when your essay takes a side, and narrow enough to support in the space you have. It states your point instead of announcing the topic.
Thesis statement examples
One example for each kind of essay. Each names a specific subject, a clear point and the reason behind it.
Argumentative
Public high schools should require uniforms because they reduce clothing-based bullying and ease the financial pressure on families.
Persuasive
Cities should ban single-use plastic bags, because the small inconvenience to shoppers is worth the cleaner streets and waterways a ban delivers.
Expository
Vaccines protect the body by training the immune system to recognize a germ before a real infection, so it can respond faster and more strongly.
Analytical
In The Great Gatsby, the green light shows that the American Dream stays out of reach, because it loses its power the moment Gatsby gets close to it.
Compare and contrast
Online classes suit working students better than in-person classes, but in-person classes do more to build the motivation and community that help students finish.
Cause and effect
Rising rents in city centers are pushing young families to the suburbs, which lengthens their commutes and weakens the neighborhood schools they leave behind.
Research paper
Among university students, using social media for more than 30 minutes before bed is linked to poorer sleep quality, even after accounting for caffeine and study hours.
How to write a thesis statement, step by step
Step 1
Start with a question
Turn your topic or assignment into a question your essay will answer, such as: should schools require uniforms?
Step 2
Answer it in one sentence
Write your answer as a clear claim. This is your working thesis.
Step 3
Add your reason
Say why your answer is true, or name the main points you will use to support it.
Step 4
Make it specific
Replace vague words like good, bad or important with exactly what you mean, and name who or what you are writing about.
Step 5
Check the scope
Make sure you can support the claim in the length you have. Narrow a broad topic to one group, place or period.
Step 6
Revise as you write
Your thinking will sharpen as you draft. Come back to your thesis and update it so it matches the essay you wrote.
Strong vs weak thesis statements
Small changes make a big difference. Here is what separates a weak thesis statement from a strong one.
Weak
Social media is used by many teenagers.
Strong
Heavy social media use at night harms teenagers’ sleep because endless feeds push back their bedtimes.
Why: the weak one is a fact no one would dispute. The strong one makes a claim and gives a reason.
Weak
This essay will discuss school uniforms.
Strong
Public high schools should require uniforms because they reduce clothing-based bullying.
Why: the weak one announces the topic. The strong one states the point itself.
Weak
Technology has changed the world.
Strong
Smartphones make it harder for high school students to focus in class because notifications keep interrupting their attention.
Why: the weak one is too broad for any essay. The strong one names a specific technology, group and effect.
Weak
Climate change is bad.
Strong
Coastal cities should limit new construction in flood-prone areas, because building there puts residents and public budgets at growing risk.
Why: the weak one rests on a vague word. The strong one says exactly what should happen and why.
