What a topic sentence does

A topic sentence is usually the first sentence of a body paragraph. It states the paragraph’s single controlling idea and links it back to the thesis, so the reader knows what the next few sentences will prove.

Frequently asked questions

What is a topic sentence?

The sentence, usually first in a paragraph, that states the paragraph’s main idea. Every other sentence in the paragraph should support it.

How do you write a good topic sentence?

Name one specific point, connect it to your thesis, and keep it to one sentence. Avoid announcing (“This paragraph will discuss…”) and avoid facts that leave nothing to argue.

Is a topic sentence the same as a thesis?

No. The thesis states the main argument of the whole essay; a topic sentence states the point of one paragraph that supports it.

Is it free?

Yes, free with no signup.
