There are many types of paragraphs that serve different purposes. Some common types include argumentative paragraphs that seek to convince the reader of something, descriptive paragraphs that describe people, places or things in detail, and explanatory paragraphs that explain a subject thoroughly to teach or inform readers. Paragraphs can also be introductory, concluding, narrative, comparative, deductive, inductive and more. Well-structured paragraphs generally include a topic sentence expressing the main idea supported by additional details and examples.
