Origin
1580-1590
1580-90; < Latin oppōnent- (stem of oppōnēns, present participle of oppōnere to place over, against, or in front of, make an obstacle), equivalent to op- op- + pōn(ere) to place, set, put + -ent- -ent
Synonyms
1. antagonist. Opponent, competitor, rival refer to persons engaged in a contest. Opponent is the most impersonal, meaning merely one who opposes; perhaps one who continually blocks and frustrates or one who happens to be on the opposite side in a temporary contest: an opponent in a debate. Competitor emphasizes the action in striving against another, or others, for a definite, common goal: competitors in business. Rival has both personal and emotional connotations; it emphasizes the idea that (usually) two persons are struggling to attain the same object: rivals for an office.
Antonyms
1. ally, friend.
