Synonym discussion
Sense: noun/1
Rivalry suggests a long-term, often personal relationship in which each side tries to prove itself better than the other — for example, the rivalry between two neighbourhood restaurants that have been competing for customers for years. Competition is the broadest term and can describe anything from a single chess match to market forces; it does not imply a personal relationship. Contest refers to a specific, structured event with a clear winner (a spelling contest, a cooking contest). Antagonism is more hostile and focuses on the emotional state of opposition rather than on outperforming someone: two colleagues may feel antagonism toward each other without actively competing for anything. Use rivalry when the relationship has history, competition for a general situation, contest for a structured event, and antagonism for hostile feelings.

Etymology
Rivalry comes from the Latin word rivalis, meaning 'a person who uses the same stream as another.' In ancient Rome, neighbours who shared a river or stream (rivus) would often quarrel over water rights, so rivalis came to mean 'a competitor.' The word passed through French (rivalité) before entering English in the 1500s with the meaning of competition between people or groups.
