What does acerbate mean?
Acerbate is a formal verb meaning to embitter — to fill someone with bitterness, resentment, or irritation. Derived from the Latin acerbus, meaning harsh, bitter, or sour, it entered English in the early seventeenth century and belongs to the same family as the adjective 'acerbic', used today for sharply cutting wit. In modern English acerbate is uncommon and largely literary; most writers reach instead for its close relative 'exacerbate' when they want to say that something has been made worse. Where acerbate retains value is precisely in its narrower, more emotional force: it describes not a situation deteriorating but a person's temper being soured. Repeated slights can acerbate old grievances; a patronizing tone can acerbate an already tense negotiation. Because of its rarity and elegance, using it well signals precision and vocabulary depth, but speakers should be aware that many listeners will mistake it for 'exacerbate'.

Acerbate and 'acerbic' share the same Latin root as vinegar-sharp sourness — this is literally the verb form of turning someone's mood tart.
