What is the Latin term for a barber?

The correct term for a barber in Latin is "tonsor." This word derives from the verb "tondēre," which means "to shear" or "to clip," indicating the primary function of a barber—cutting hair and shaving. The role of a tonsor was significant in Roman society, where barbershops (tonstrina) served as social hubs where men could gather not just for grooming but also to converse and discuss matters of the day.

The other options represent different occupations or roles. "Carnifex" refers to an executioner or butcher, "publicanus" denotes a tax collector, and "pistor" means baker. Each of these terms relates to distinct professions, but none connects to grooming or hair cutting, which is the defining element of the role of a barber. Thus, "tonsor" stands out clearly as the appropriate choice.
