What does undefeated mean?
Undefeated describes someone or something that has never lost, most often in a contest, competition, or battle. A team that completes a season undefeated has won every game; a player described as undefeated has not lost a match or tournament. The word is especially common in sport but can also refer to armies, political campaigns, or other forms of rivalry. Undefeated focuses on an actual record of non-defeat, whereas unbeatable suggests that defeat is impossible. The term carries positive connotations of strength, consistency, and excellence, although it can also imply that a rival has not yet succeeded in overcoming the subject. It is usually used attributively, as in undefeated champion, or predicatively, as in the team remains undefeated.

Where does undefeated come from?
Undefeated was formed in English by adding the prefix un-, meaning 'not,' to the past participle defeated. The word defeat comes through Old French from Latin defacere, formed from dis- and facere, with the sense of destroying or undoing. The related forms defeatism and defeatist developed from the same historical root, though they now describe a contrasting attitude or approach.
