Why “vitiation” is a great word
VITIATION — [Noun] The act of impairing the quality, validity, or purity of something, or the state of being so impaired. From Latin vitiare ("to spoil, damage, corrupt") + the noun-forming suffix -tion. Unlike "corruption," which implies a pervasive, often moral decay, or "nullification," which denotes making something legally void, vitiation is the precise, technical process of introducing a fatal flaw. It is the hidden fallacy that unravels a proof, the undisclosed bias that voids a contract, or the faint sour note that spoils a vintage—the quiet, irrevocable entry of flaw into what was once sound.
