What does tainted mean?
Tainted means that something has been affected by corruption, contamination, or another harmful influence. Its most familiar use is figurative: a person's reputation, evidence, or organization may be described as tainted when misconduct or improper dealing compromises its trustworthiness. In physical contexts, tainted food, water, or air has been contaminated or made unsafe or unsuitable. The word has a strongly negative connotation and is often associated with moral corruption, dishonesty, or decay, giving it more force than a neutral description such as affected. Tainted is the past participle and past-tense form of the verb taint, as in “the allegation tainted the inquiry.” The term is used in both British and American English and is especially common in legal, political, journalistic, and everyday discussions of integrity and safety.

Where does tainted come from?
Tainted developed from the verb taint, which comes through Old French from Latin tingere, meaning “to touch,” “to tint,” or “to color.” The English noun taint originally referred to a spot, stain, or discoloration before extending metaphorically to moral or physical corruption. Related English words include tint and tincture, which share the same Latin root.
