Old English moððe (Northumbrian mohðe), common Germanic (Old Norse motti, Middle Dutch motte, Dutch mot, German Motte "moth"), perhaps related to Old English maða "maggot," or from the root of midge (q.v.). Until 16c. used mostly of the larva and usually in reference to devouring clothes (see Matt. vi:20).
