A "blurb" is a short written description or promotional piece that summarizes the content of a book, article, film, or other work. It is typically found on the back cover of books or in advertisements, aiming to attract readers' attention and give them a sneak peek of the work's themes or plot.
The word "blurb" was coined in 1907 by author Gelett Burgess. It is thought to be a play on the words "blurb" and "flurb," and it initially referred to a humorous or facetious description of a book.
