There are five types of paragraphs: descriptive, example, process, opinion, and narrative. A typical paragraph includes a topic sentence that introduces the topic, supporting sentences that further explain the topic, and a concluding sentence that restates the main idea. Key elements of formatting a paragraph properly include margins, double spacing, indenting the first sentence, and connecting sentences together with similar topics within the same paragraph. Effective topic sentences should be clear, short, and introduce a new controlling idea about the topic without stating simple facts or specific details. Supporting sentences add information to further the topic and controlling idea, while concluding sentences remind the reader of the main point and may restate or comment on the topic.
