Quash is a verb that means ‘to put an end to.’

The Latin word cassus (cah SOOSE) means ‘null and void.’ Our word of the day emerged during the middle English period and has since been used as a verb and often in a legal context. Here’s an example:

The lawsuit was quashed when it became clear the plaintiff had no evidence. I’m no lawyer, but even I know that if you have no evidence, you have no case.
