Origins

Meanings 1–4, 6–8, 12–14, 17–20

From Middle English part, from both Old English part and Old French part, both from Latin partem, the accusative of pars ("piece, portion, share, role, part"), possibly from a Proto-Indo-European root meaning "to sell, exchange." It is often linked with Latin portiō ("a portion") and parāre ("to prepare"), though both connections are disputed.
