What does causticness mean?
Causticness is the quality of being caustic, most often used for language that is sharp, cutting, or sarcastic. It names the abrasive character of a remark rather than the remark itself, and it commonly carries the implication that the criticism is intentionally severe or unkind. A critic may be praised for incisive analysis while being criticized for causticness, which suggests that the force of the language has become excessive. Less commonly, causticness can describe the burning or corrosive quality of a substance, although corrosiveness is the more usual term in technical contexts. The word is useful when discussing tone because it distinguishes a particular kind of harshness from mere rudeness: caustic language is characteristically pointed, stinging, and abrasive. It is also related etymologically to the same Latin and Greek vocabulary underlying caustic, meaning burning and sharply irritating.
