[C15: from Old French parcial, from Late Latin partiālis incomplete, from Latin parspart]
early 15c., "one-sided, biased," from O.Fr. parcial (14c.), from M.L. partialis "divisible, solitary, partial," from L. pars (gen. partis) "part" (see part (n.)). Sense of "not whole, incomplete" is attested from mid-15c. (implied in partially "incompletely").
