Usage Note

Common Mistakes

He is a competitor in the swimming race.
'challenger' implies someone specific is trying to take a title from an existing champion or holder; 'competitor' is the correct word for any participant in a contest without a reigning title-holder.

Sense: noun/1

All four words refer to someone taking part in a contest, but they differ in key ways. A challenger specifically targets an existing title-holder — the word makes no sense if there is no champion or incumbent to defeat ('the challenger to the throne'). A contender also has a realistic shot at winning but does not require a reigning champion ('a top contender for the gold medal'). Competitor is the broadest term, covering anyone in a race or tournament regardless of status. Rival emphasises a long-term, often personal, competitive relationship between two parties ('business rivals for ten years'). Use challenger when the focus is on unseating a current title-holder; use contender when discussing someone's odds of winning; use competitor for neutral participation; and use rival for a repeated head-to-head relationship.

Etymology

LatinOld FrenchEnglish

The word comes from Old French 'chalengeour', meaning 'one who makes a claim or accuses', which itself came from Latin 'calumniator' (one who brings false accusations). Over time, the legal sense of 'summoning someone to answer a claim' shifted into the sporting and competitive sense of 'inviting someone to a contest'. By the 1500s, 'challenger' was used in English for someone who formally calls out a title-holder to a fight or competition.
