Origin & History of “elf”
In Germanic legend, elves were potent supernatural beings, capable of exercising considerable magic powers to the benefit or harm of human beings. Their decline to their modern status as small mischievous sprites seems to have begun in the 16th century. The word comes from a prehistoric Germanic *albiz, a variant of which produced Old Norse álfr (source of English oaf (17th c.)) and German alp ‘nightmare’.
