Pointy ears or pointed ears are a characteristic of many animals, a genetic disorder in humans, as well as a cliché in popular culture, particularly in the fantasy genre. They are commonly known as "elf ears".
An elf is a type of humanoid supernatural being in Germanic folklore. Elves appear especially in North Germanic mythology, being mentioned in the Icelandic Poetic Edda and Snorri Sturluson's Prose Edda.
