What is the primary function of headings in written material?

The primary function of headings in written material is to guide comprehension. Headings serve as clear markers that help organize and structure the text, making it easier for readers to follow the main ideas and identify the topics being discussed. They break down complex information into manageable sections, allowing readers to quickly locate specific content and understand the overall organization of the material. This structured approach enhances understanding and supports better retention of the information presented. Effective headings can also set expectations about what follows, helping readers grasp the significance of the content within each section.
