One who is defeated; a person or team that loses a competition or conflict.
From defeat + -ee (one who is acted upon). A modern formation that parallels words like employee or addressee, referring to the person on the receiving end of defeat.
This word is genuinely rare in standard English—we prefer saying 'loser' or 'defeated person.' But it appears in technical sports analysis and game theory because it precisely distinguishes who did the defeating from who got defeated. It's the grammatical opposite of 'defeater.'
