IPA: /ˈraɪvəlri/
KK: /ˈraɪvəlri/
The situation in which two or more people or groups compete against each other for the same goal or prize.
The rivalry between the two teams has lasted for decades.
Rivalry is formed from "rivalis" (meaning one who uses the same stream) and the suffix "-ry" (indicating a state or condition). The word originally described the condition of competing for the same resources or goals, particularly in the context of water rights.
Think of 'rivalis' as someone who shares the same stream, which helps you remember that 'rivalry' is about competing for the same things.
