The `a’ in the first syllable is like the `a’ in `amount’ and account’; the `cer’ sounds like the word `sir’. The final `ic’ is like the `ick’ in `stick’, `chick’, and `kick’, and the main stress is on the second syllable. The word is pronounced `asirbick’. It comes from the Latin acerbus’ meaning `harsh’.
When you say that someone’s comments were `acerbic’, what you mean is that they were cruel, stinging or bitter tasting.
Examples: Ram’s acerbic wit has made him many enemies.* *Despite the acerbic reviews, Usha’s latest book has become a bestseller.
