corrosive

This term describes a destructive process of gradual erosion. In a chemical sense, it evokes the image of a substance eating through a surface, leaving it pitted, weakened, or entirely dissolved. It is most frequently used in industrial or scientific contexts to describe acids and bases. When applied to human interaction, the word shifts from physical destruction to emotional damage. It describes a type of sarcasm or criticism that does not just hurt momentarily but slowly wears down a person's confidence or a relationship's stability, mirroring the slow decay of metal.
