Fairies

A fairy (also fay, fey, faery, faerie; collectively, "fae", wee folk, good folk, people of peace, fair folk and other euphemisms) is a type of being or legendary creature, a form of spirit, often described as metaphysical, supernatural or preternatural

The word fairy derives from the term fae of medieval Western European (old French from Latin fata: Fate) folklore and romance. "Fae-ery" was therefore everything that appertains to the "fae". Finally the word replaced its original and one could speak of "a faery or fairy", though the word fey is still used as an adjective or to refer to the word fairy as a plural.
