unspotted
UK: ʌnˈspɒtɪd | US: ʌnˈspɑːtɪd
adj. free from spots or stains; physically clean
adj. morally pure or blameless
adj. not noticed or observed
The word "unspotted" combines the negative prefix "un-" (Old English "un-," meaning "not") with "spot" (from Old English "splot," meaning a mark or stain) and the adjectival suffix "-ed" (indicating a state or condition). Originally used literally to describe something physically clean, it later evolved metaphorically to imply moral purity or something going unnoticed. The progression reflects a shift from concrete visual absence to abstract qualities.
