The word fairy derives from Middle English faierie (also fayerye, feirie, fairie), a direct borrowing from Old French faerie (Modern French féerie) meaning the land, realm, or characteristic activity of the legendary people of folklore and romance called (in Old French) faie or fee (Modern French fée). This derived ultimately from Late Latin fata (one of the personified Fates, hence a guardian or tutelary spirit, hence a spirit in general); cf. Italian fata, Spanish hada of the same origin.
Fairies are generally described as human in appearance and having magical powers. I don’t know about you, but I was always fond of fairies. Maybe because they are usually presented as beautiful girls, and they are almost always cute, adorable and sexy
