1. acid

   Acid, sour, and bitter agree in being contrasted with sweet, but the two former are sharply distinguished from the latter. Acid or sour is the taste of vinegar or lemon-juice; bitter that of quassia, quinine, or strychnine. Acrid is nearly allied to bitter. Pungent suggests the effect of pepper or snuff on the organs of taste or smell; as, a pungent odor. Caustic indicates the corroding effect of some strong chemical, as nitrate of silver. In a figurative sense, as applied to language or character, these words are very closely allied. We say a sour face, sharp words, bitter complaints, caustic wit, cutting irony, biting sarcasm, a stinging taunt, harsh judgment, a tart reply. Harsh carries the idea of intentional and severe unkindness, bitter of a severity that arises from real or supposed ill treatment. The bitter speech springs from the sore heart. Tart and sharp utterances may not proceed from an intention to wound, but merely from a wit recklessly keen; cutting, stinging, and biting speech indicates more or less of hostile intent, the latter being the more deeply malicious. The caustic utterance is meant to burn, perhaps wholesomely, as in the satire of Juvenal or Cervantes. Compare MOROSE.

   acerb, acetous, acidulated, acidulous, acrid, acrimonious, biting, bitter, caustic, cutting, harsh, irate, pungent, savage, sharp, sour, stinging, tart, vinegarish, virulent

   Antonyms:

How to use acid in a sentence?

1. Lund University researcher Tobias Olofsson:

   Well, we've seen in our research that the honey bees actually add great flora of lactic acid bacteria in honey so the mead, when produced, is actually fermented by these lactic acid bacteria together with wild yeasts and the lactic acid bacteria can really kill off all the dangerous pathogens that are even resistant against antibiotics. So our thinking is that the mead, when you consume the mead, these (antibacterial substances in) lactic acid bacteria in the drink can actually be transferred to your blood and help you when you are infected with dangerous bacteria or promote health, preventing infections.
