A paragraph is a group of sentences all about the same idea. Each paragraph starts with a topic sentence that introduces the main idea. Then come supporting sentences that give details, examples or reasons. A concluding sentence may wrap up the idea. A new paragraph is started for each new idea, beginning on a new line (and often indented).
