Where it comes from
Used in English since the 16th century. From Middle French moustache from Italian mostaccio, from Early Medieval Latin mustācium, from Byzantine Greek μουστάκιον (moustákion), diminutive of (Doric) Ancient Greek μύσταξ (mústax, “upper lip”), of unknown origin (probably a Pre-Greek substrate). Replaced native English kemp (“moustache”), from Old English cenep.
