reject (v.)
early 15c., from Old French rejecter and directly from Latin reiectus, past participle of reiectare "throw away, cast away, vomit," frequentative of reicere "to throw back," from re- "back" (see re-) + -icere, comb. form of iacere "to throw" (see jet (v.)). Related: Rejected; rejecting.
reject (n.)
1550s, "a castaway" (rare), from reject (v.). Modern use probably a re-formation of the same word: "thing cast aside as unsatisfactory" (1893); "person considered low-quality and worthless" (1925, from use in militaries).
