I love playing racquetball with my friends on the weekends.
Racquetball is formed from "racquet" (from Old French *raquette*, meaning a type of bat or paddle) and "ball" (from Old English *beall*, meaning a spherical object used in games). The word describes a sport played with a racquet and a ball.
Think of a 'racquet' used to hit a 'ball' in a game — that's how you remember that racquetball is a sport involving both.
