Etymology

From Middle English part, from Old English part (“part”) and Old French part (“part”); both from Latin partem, accusative of pars (“piece, portion, share, side, party, faction, role, character, lot, fate, task, lesson, part, member”), from Proto-Indo-European par-, per- (“to sell, exchange”). Akin to Latin portiō (“a portion, part”), parāre (“to make ready, prepare”). Displaced Middle English del, dele (“part”) (from Old English dǣl (“part, distribution”) > Modern English deal (“portion; amount”)), Middle English dale, dole (“part, portion”) (from Old English dāl (“portion”) > Modern English dole), Middle English sliver (“part, portion”) (from Middle English sliven (“to cut, cleave”), from Old English (tō)slifan (“to split”)).

From Middle English parten, from Old French partir.
