A "chapter" is a distinct section of a written work, such as a book or a report. Chapters help organize content, making it easier for readers to follow the narrative or argument. Each chapter typically focuses on a specific theme or topic, allowing for a structured progression of ideas. In literature, chapters often have titles or numbers that indicate their order. They can vary in length and may include subheadings to further divide the content. Authors like J.K. Rowling and George R.R. Martin use chapters to build suspense and develop characters throughout their stories.
