Taintless → It is formed from "taint" (from Old French *teindre*, meaning to dye or stain) and "-less" (meaning without). The word "taintless" means without stain or blemish, referring to purity or cleanliness.
Think of being 'without' ('-less') any 'stain' ('taint') — that's why taintless means pure or clean.
