'barbermonger' originates from English as a compound of 'barber' + 'monger', where 'barber' ultimately comes from Latin 'barba' meaning 'beard' (via Old French 'barbier') and 'monger' comes from Old English 'mangere' meaning 'seller'.

'barber' came into English via Old French 'barbier' from Latin 'barba'; 'monger' derives from Old English 'mangere' (seller). These elements were combined in Early Modern English to form the compound 'barbermonger', used to denote someone who cut hair or sold barbering wares.

Initially it referred specifically to a person who practiced barbering or sold barbering supplies (often itinerant). Over time the compound fell out of common use and the simple term 'barber' (or more specific terms) replaced it; 'barbermonger' is now archaic.
