Etymology

Origin of brash

First recorded in 1400–50; (noun) late Middle English brass(c)he “a slap, crash,” perhaps blend of brok(e) ( Old English broc “breach, fragment, sickness”; akin to break ) and dasch “smashing blow”; see dash 1; (adjective) in the sense “brittle” is derivative of the noun; in the sense “hasty” by confusion with rash 1

Explanation

Brash sounds like what it means: harsh, loud, and maybe a little rude. Sometimes that’s good, like when you have a serious rash on your face and give Aunt Nell a brash warning before she showers you with kisses. There's nothing warm and fuzzy about brash. New Yorkers are sometimes thought of as the poster children for brash behavior: they can be bold and brazen. Pushy even. You might find brashness offensive, or maybe you think it's refreshingly direct. If you're a cab driver, a tough exterior might be useful, but being brash probably won’t advance your career if you work in a hotel, where you’re supposed to be polite and welcoming.
