What does defiled mean?
'Defiled' is the past tense and past participle of the verb 'defile', meaning to make something dirty or impure, and by extension to violate its sanctity or moral integrity. It operates on two levels: the literal sense of physical contamination — a spring defiled by sewage, for instance — and a stronger figurative sense of desecration or moral corruption, as when a temple is defiled by invaders or a person's good name is defiled by slander. Because of this second sense, the word carries heavy, solemn connotations and appears most often in religious, historical, or literary writing rather than everyday conversation. Its emotional force lies in implying that what has been defiled was once pure, sacred, or honorable, and that the violation was deliberate or grievous. The adjective form describes things already in that state: 'the defiled altar', 'a defiled legacy'. Related forms include the noun 'defilement' and the agent noun 'defiler'.

Etymology of defiled
'Defile' came into English in the late Middle Ages from Old French 'defouler'/'defiler', ultimately built on the Latin root 'filum', meaning thread — the underlying image being of something dragged along the ground like a filthy thread. The same Latin root gives English 'filament', 'filigree', and 'profile'. Over time the word shifted from physical fouling toward moral and religious violation, which is now its dominant register.
