Did You Know?
There are two quash verbs in English, and although their meanings are vaguely similar, they have entirely different origins. Both essentially mean to get rid of something—you can quash a rumor, for example, or you can quash a judicial order. The legal term quash (defined above) comes from an Anglo-French word, casser, meaning "to annul," and ultimately from Latin cassus, meaning "void." The other quash means "to suppress or extinguish summarily and completely." It derives from the Middle English word quashen, meaning "to smash," and ultimately from a form of the Latin verb quatere, meaning "to shake."
