There are four main types of paragraphs: narrative, descriptive, expository, and persuasive. Narrative paragraphs tell a story or sequence of events. Descriptive paragraphs provide details to describe people, objects, or scenes. Expository paragraphs provide information to explain, define, compare, or show relationships. Persuasive paragraphs aim to convince readers by sharing opinions and trying to influence beliefs or actions.
