tonsorial

Tonsorial is a fancy word that describes the work of those who give shaves and haircuts. (It can apply more broadly to hairdressers as well.) It derives from the Latin verb tondēre, meaning "to shear, clip or crop." (Another descendant, "tonsor," is an archaic word for a barber.) You might be more familiar with the related noun "tonsure," which refers to the shaven crown or patch worn by monks and other clerics, or the religious rite of clipping the head of one being admitted as a cleric. The verb tonsure means "to shave the head of."
