Subheadings are titles or phrases that break up sections of text within a document, article, or book. They help organize content, making it easier for readers to navigate and understand the main ideas. By using subheadings, writers can highlight key points and guide readers through the material without overwhelming them with large blocks of text. In addition to improving readability, subheadings can enhance the overall structure of a piece. They allow for a clearer presentation of information, making it easier for readers to locate specific topics. This is especially useful in longer works, such as research papers or instruction manuals, where clarity is essential.
