In your own words briefly explain fairy tales

A fairy tale is a story, often intended for children, that features fanciful and wondrous characters such as elves, goblins, wizards, and even, but not necessarily, fairies. ... Fairy tales are often traditional; many were passed down from story-teller to story-teller before being recorded in books.
