taint
UK: teɪnt | US: teɪnt
n. a trace of something bad or harmful
vt. to contaminate or pollute; to spoil or damage morally
The word "taint" originates from Old French teint, meaning "dyed" or "stained," derived from Latin tingere ("to dye, moisten"). Over time, its meaning shifted from physical staining to metaphorical contamination or corruption, reflecting the idea of something pure being "colored" by impurity. The spelling and core concept have remained consistent, emphasizing the irreversible nature of spoilage.
