The word "moustache" derives from 16th century French moustache, which in turn is derived from the Italian mostaccio (14th century), dialectal mustaccio (16th century), from Medieval Latin mustacium (8th century), Medieval Greek μουστάκιον (moustakion), attested in the 9th century, which ultimately originates as a diminutive of Hellenistic Greek μύσταξ (mustax, mustak-), meaning "upper lip" or "facial hair",[2] probably derived from Hellenistic Greek μύλλον (mullon).
