As a noun, squash is of course the instance and act of squashing, but it is also a sport for two or four people played with rackets. Unrelatedly, a squash is a type of vegetable, actually the fruit of a plant of the gourd family, eaten as a vegetable. In UK English, squash is also a type of cordial (a sweet, concentrated, fruit-based drink) that is diluted with water and drunk.
