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 clarity and flow, guiding the reader through the author's arguments or narratives. Proper paragraphing enhances the overall coherence of the text, making it more engaging and accessible to the audience.
