topic sentence

Main idea statement

A topic sentence states the main idea of a paragraph, typically appearing at the beginning to guide readers through what follows.

It functions like a miniature thesis for that paragraph.

In academic and expository writing, teachers emphasize topic sentences as tools for organizing ideas: Each paragraph should have a clear topic sentence.
