Etymology

Origin of elf

First recorded before 1000; Middle English, from Old English ælf, elf, ylf, akin to Old High German alp “incubus” ( Middle High German alp , German Alp “nightmare”), Old Norse álfr, Danish alf “elf” ælfen; elfin

Explanation

An elf is a mythological creature that's said to be tiny, magical, and a little mischievous. Elves are not just known for giving Santa a hand. In fact, ancient Anglo-Saxon medical books ascribed some illnesses to elves. Old English texts often blamed elves for sharp pains and mental disturbances — they were said to cause illness with sharp weapons, such as arrows. The folklore and myths of Scotland, Iceland, and Germany are particularly famous for the inclusion of elves. An elf's tiny size has also led to the use of elfin or elf-like to describe a small person's features: "His little elfin nose was so cute."
