Did you know?

We would be culpable—that is, deserving of blame—if we didn’t clearly explain the origin of culprit. Yes, it is related to culpable, which itself comes (via Middle English and Anglo-French) from the Latin verb culpare, meaning “to blame.” But the etymology of culprit is not so straightforward. In Anglo-French, culpable meant “guilty,” and this was abbreviated “cul.” in legal briefs and texts. Culprit was formed by combining this abbreviation with the Anglo-French word prest or prit, meaning “ready”; literally, a culprit was one who was ready to be proven guilty. The word was eventually adopted into English and used to refer to someone who is accused of a wrongdoing. The word has since taken on an additional meaning: “the source or cause of a problem.”
