Answer:
An author is a person who writes books or articles, usually for money. It can also refer to the person responsible for something, like the author of a plan to overthrow the student government.
Author comes from the Latin word auctorem, meaning "founder, master, leader." Bow down to the author! Well, no need for that, just make sure the author gets credit. Author usually refers to a professional writer. In fact, author can be used interchangeably with the word writer. But author packs a little more punch — an author is involved in the creation of the work and generating the ideas behind it; strictly speaking, a writer could just execute the written product.
