Where it comes from
Inherited from Middle English mule, from Anglo-Norman mule (“she-mule”) and Old English mūl, both ultimately from Latin mūlus, from Proto-Indo-European *mukslós. Compare Late Latin muscellus (“young he-mule”), Old East Slavic мъшкъ (mŭškŭ, “mule”), Ancient Greek (Phocian) μυχλός (mukhlós, “he-ass”), and German Maul Maultier, Maulesel (through Latin).
