Etymology

Origin of part

First recorded before 1000; (noun) Middle English (from Old French, from Latin ), Old English, from Latin part- (stem of pars ) “piece, portion”; (verb) Middle English parten, from Old French partir, from Latin partīre, derivative of pars

Explanation

A part is a section or portion of something larger. When you injure a body part, you only hurt one arm or foot, rather than your entire body. Part can be used to mean a section of a whole, like a bicycle part, or Part Six of your book. To an actor, a part is a role in a movie or play, and to a hair stylist, it's the line on your scalp where your hair is combed in opposite directions. As a verb, it means "to divide or separate," and the Latin root is partem, "a part or portion."
