Etymology

Origin of crude

First recorded in 1350–1400; Middle English, from Latin crūdus “uncooked, raw, bleeding, rough,” akin to cruor “blood from a wound”; see raw

Explanation

Is it gross? Unsophisticated? Totally tasteless and positively offensive? Then you can describe it as crude. Crude is not rude when it’s used to describe unprocessed oil, which it first was associated with in 1865. From the Latin crudo, meaning "rough, raw," crude today can be used to describe anything or anyone that's unrefined and rough around the edges. So don’t be too insulted by the large-nosed portrait that cartoonist made for you. It’s just a quick, crude drawing meant to be funny.
