Terminology varies by sport and by country and language.
For you it might be a match, a fixture, a game, a matchup or a meet.
You can change all of the text in the public league website to be your preferred language, you can not change the language in the admin pages though.
Setup > Settings > Terminology (tab)
Entering text here will change the text on your league website.
There are quite of lot of entries on this page so search for your text using the browser search e.g. Ctrl F on google chrome
