acerbic in Context

"Whether she's giving a sarcastic eye-roll, tossing off an acerbic zinger, or seducing with a come-hither stare, [actress Jennifer] Simard intimately understands the art of underplaying." — Christopher Wallenberg, The Boston Globe, 1 June 2025

Did You Know?

English speakers created acerbic in the 19th century by combining the adjective acerb with the suffix -ic-. Acerb had already been around for a couple centuries, but for most of that time it had been used only to describe foods with a sour taste. (Acerb is still around today, but now it's simply a less common synonym of acerbic.) Acerbic and acerb ultimately come from the Latin adjective acerbus, which can mean "harsh" or "unpleasant." Another English word that comes from acerbus is exacerbate, which means "to make more violent or severe."
