An author is a person who writes books, articles, stories, or other literary works, and is responsible for the creative content of their work. The term "author" is often used to refer to someone who has published a book or other written work, but it can also be used more broadly to describe anyone who writes creatively or professionally.

Authors may write in a variety of genres, including fiction, non-fiction, poetry, and academic works. They may work independently or as part of a team, and may be self-published or work with a publishing company to produce their work. Many authors also engage in public speaking, book tours, and other promotional activities to promote their work and connect with readers.
