elf

very low-frequency electromagnetic radiation emitted by electrical appliances

n. small mischievous creature (also about a child); fairy, sprite, gnome (Folklore)

An elf is a creature of Germanic mythology which still survives in northern Europe. The elves were originally a race of minor nature and fertility gods, who are often pictured as youthful-seeming men and women of great beauty living in forests and underground places and caves, or in wells and springs. They have been portrayed to be long-lived or immortal and as beings of magical powers. Following J. R. R. Tolkien's influential The Lord of the Rings—in which a wise, angelic (and human-sized) people named Elves have a significant role—elves became staple characters of modern fantasy (see Elves in fantasy fiction and games).
