vitiation
Spoiling something's purity
Vitiation is the act of impairing, spoiling, or invalidating something.
In legal contexts, vitiation renders a contract or agreement void—fraud vitiates consent.
More broadly, anything that corrupts or degrades can vitiate: Bias vitiates the research.
The word carries a formal tone, appearing most often in legal and academic writing.
