Etymology
The word "unstained" is a Modern English formation built upon the older word "stain," which entered Middle English from Old French. The French term evolved from the Vulgar Latin extingere, a derivative of the Classical Latin verb tingere, meaning "to dip, to moisten, or to dye." The core concept of applying color or taint is preserved. The Germanic negative prefix "un-" was added to create the opposite meaning, a common pattern in English word formation. The suffix "-ed" converts the verbal idea into an adjectival state, resulting in the complete sense of "not having been marked, colored, or tainted."
