Yesterday’s word
The word acerbate means “irritate, exasperate”
Background
This word came from Latin acerbus (harsh or bitter). This word, which sounds similar to ‘exaserbate’ (to make worse), is sometimes used in place of it, but this meaning hasn’t made it into the dictionaries yet. Such usage may be an error, but it’s a good error; both words come from the same Latin root.
First usage
This word came into English in the mid-1700s
