moustache (English)

Where does "moustache" come from?

The English word 'moustache' has been used since the sixteenth century[1]. It entered English as a borrowing from Middle French 'moustache', which came from Italian 'mostaccio'[1]. This Italian form descends from Early Medieval Latin 'mustācium', itself derived from Byzantine Greek 'μουστάκιον'[1]. That Byzantine term originated as a diminutive of Ancient Greek 'μύσταξ', meaning 'upper lip'[1]. The ultimate origins of the Ancient Greek term remain unknown, though scholars suggest it stems from a Pre-Greek substrate[1]. This historical form replaced the native English word 'kemp', which meant 'moustache' and came from Old English 'cenep'[1].

Open questions

• The ultimate origin of the Ancient Greek term in a Pre-Greek substrate is uncertain and based on structural variants. [1] [3]
