Racecourse → It is formed from "race" (from Old French *racier*, meaning to run) and "course" (from Latin *cursus*, meaning a running or a course). The word "racecourse" refers to a track or area where races are held, specifically for running or racing events.
Think of a place where people 'run' ('race') along a designated 'course' — that's what a racecourse is.
