What does quashing mean?
Quash means to put an end to something by suppressing it, preventing its continuation, or declaring it invalid. The verb is used particularly in legal contexts: a court may quash a conviction, ruling, indictment, or order, meaning that the decision is set aside and treated as invalid. In broader contexts, someone may quash a rebellion, protest, rumour, or attempt to organize opposition, with the implication that it is stopped firmly and decisively. The word has a formal, authoritative tone and often suggests a decisive intervention rather than a gradual resolution. Although it can be paired with a wide range of objects, it is especially established with legal proceedings and decisions. Understanding both its general and legal senses helps distinguish it from similar words: quashing a ruling invalidates it, while overturning it may involve replacing it with a different decision, and suppressing an uprising may mean ending it without necessarily declaring it unlawful.

Where does quashing come from?
Quash derives from the Old English verb cwædan, meaning to crush, break, or destroy. It entered Middle English in the form quassen and developed into the modern spelling quash. The word originally conveyed the idea of physically crushing something, which later broadened to the modern senses of forcefully suppressing or invalidating something.
