What is a "flap"?

A flap is a portion of the cover or dust jacket that extends beyond the edges of the book's pages. It is typically used to hold additional information, such as a synopsis, author biography, or promotional details. Flaps can also help protect the book's cover by folding over and tucking into the book, securing it in place. This feature is common on hardcover books and dust jackets, adding both functional and decorative elements to the book's design.
