What is a paragraph header

A heading is similar to a caption, a line below a photograph that briefly explains it. Headings show up at the top of paragraphs, chapters, or pages, and they give you an idea of what the subject is. You might write a heading for each chapter of your novel, or on each page of your Spanish club newsletter.
