Etymology: The Latin "acerbus" meant "bitter" or "sour," and it was originally a word for taste before it became one for temperament. From it came "acerbitas," a noun for harshness of taste and, by extension, of manner, and English borrowed the word through French "acerbité," which is why it reads as formal and a little austere to modern ears. The word shares its root with "acerb," an adjective for something sharp or severe in tone, so the two are close relatives that English adopted in parallel. Both carry the same core image: something that bites the tongue, whether it is an unripe fruit or a remark meant to wound.
