Etymology: "Acerbus" is a Latin adjective meaning "sour," "bitter," or "harsh to the taste," and it was applied to unripe fruit, sharp wine, and similar things before anything else. Latin writers extended it to people and experiences, so that a harsh remark or a cruel fate could also be "acerbus," and the sense of something unpleasant to undergo comes from that figurative use. The Latin word itself is generally traced to "acer," meaning "sharp" or "pungent," with the suffix "-bus" added. The same root gave English "acrid" and "acrimony," though "acerbus" passed into English more directly and kept its taste-based sense alongside the moral one.
