FAQ
Frequently Asked Questions
In contemporary English, the figurative meaning ('bitingly sarcastic') is more common in general writing and journalism. The literal meaning is largely confined to technical texts on dyeing, histology, or conservation.
Yes, but primarily in technical contexts related to dyeing and microscopy. It means 'to treat with a mordant'. Example: 'The fabric is mordanted to prepare it for the dye bath.'
Both imply scorn or cynicism. 'Mordant' emphasises a biting, corrosive quality that 'etches' its criticism. 'Sardonic' is more about grim, disdainful mockery, often accompanied by a sneering or grimly amused attitude.
In its figurative sense, it typically does, implying criticism that is harsh, sharp, and potentially hurtful. However, it can sometimes be used admiringly to describe incisive intellectual clarity or effective satire ('mordant wit'). The technical sense is neutral.
