What gives a reader an idea of a paragraph's content is the topic sentence, usually the first sentence, which states the main idea and acts as a signpost, preview, or headline for the rest of the paragraph, guiding the reader through the specific point the writer will develop. All other sentences in the paragraph then support or explain this main idea, ensuring the paragraph stays focused and organized.
A topic sentence essentially tells readers about the rest of the paragraph. All sentences after it have to give more information about that sentence, prove it by offering facts about it, or describe it in more detail.
The main idea is the most important idea in the paragraph. It is a fact or opinion. The main idea is usually the first or second sentence in a paragraph. This sentence is called the topic sentence.

The main idea expresses the central point, or the most important idea, in the paragraph—what the passage is about. The main idea gives the paragraph focus, purpose, and direction. The rest of the paragraph explains, develops, illustrates, or supports the main idea.
