Quash vs. squash
As a verb, squash means to beat, squeeze, press, or crush something into a flattened mass. As a noun, it denotes the family of tendril-bearing plants with leathery rinds and edible fruit, and squash is also racket game played in a closed-walled court with a rubber ball. Quash means (1) to set aside or annul by judicial action, and (2) to suppress forcibly and completely. When squash is used figuratively, its meaning can come very close to the second sense of quash.
