Did you know?

There are two quash verbs in the English language, and although their meanings are 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 (meaning "to nullify") comes from the Anglo-French words casser or quasser, meaning "to annul," and is ultimately from Latin cassus, "to void." The other quash means "to suppress or extinguish summarily and completely." It derives from the Middle English word quashen, meaning "to smash," and is ultimately from a form of the Latin verb quatere, meaning "to shake."
