IPA: //ˈriːmætʃ//
KK: /ˈriːˌmætʃ/
A second competition or game between the same players or teams that have already faced each other before.
The two boxers agreed to have a rematch after their last fight ended in a draw.
Rematch → It is formed from "re-" (meaning again) and "match" (from Old French *macier*, meaning to make equal or to pair). The word "rematch" means to match or compete again after a previous match.
Think of doing something 'again' ('re-') after a previous 'match' — that's why a rematch is a repeat competition.
