A paragraph is a distinct section of writing that typically consists of several sentences focused on a single idea or theme. It helps organize thoughts and makes the text easier to read and understand. Each paragraph usually begins with a topic sentence that introduces the main idea, followed by supporting sentences that elaborate on it. In written works, such as essays or articles, paragraphs are essential for structuring content. They provide a visual break for readers, allowing them to process information more effectively. Proper paragraphing enhances clarity and flow, making it an important aspect of effective communication in writing.
