How would one describe something that is "vitriolic"?

The term "vitriolic" relates to language or behavior that is extremely caustic or bitter, often conveying strong criticism or hostility. This word originates from "vitriol," a term for sulfuric acid, which metaphorically suggests a corrosive quality. When describing comments or discourse as vitriolic, it implies a sharpness and intensity that can injure or offend, much like acid can corrode materials.

In this context, the other choices imply more positive or neutral tones. Describing something as soft and gentle, encouraging and uplifting, or neutral and unbiased contrasts sharply with the meaning of vitriolic, which is characterized by venomous and scathing remarks. Thus, the best description aligns with the understanding of vitriolic as harsh or corrosive in tone.
