Etymology
From Late Middle English defilen (“to make dirty, befoul; rape; abuse; destroy; injure; oppress”) [and other forms], a variant of defoulen (“to make dirty, defile, pollute; have sexual intercourse with; rape; etc.”) (compare also defoilen). Defoulen is a blend of Middle English foulen (“to make dirty, soil, pollute”) (from the adjective foul (“dirty, rotten, stinking, corrupt, sinful, guilty”) and Old English fūlian (“to decay”)), and Old French defoler, defouler (“to trample, crush; destroy”), from de- (intensifying prefix) + foler, fouler, fuller (“to trample, tread on; mistreat, oppress, destroy”) (from Vulgar Latin fullāre (“to full (make cloth denser and firmer by soaking, beating, and pressing)”), from Latin fullō (“person who fulls cloth, fuller”); further etymology uncertain, possibly from Proto-Indo-European *bʰleh₃- (“to blow; to inflate, swell; to bloom, flower”) or Etruscan 𐌘𐌖𐌋𐌖 (φulu)). The English word is analysable as de- + file (“to corrupt; defile”). The Middle English word defilen was probably formed from defoulen on the analogy of befilen (“to make dirty, befoul; corrupt; violate one's chastity; desecrate; slander”) and befoulen (“to make dirty, befoul; violate one's chastity; vilify”), respectively from Old English befȳlan (“to befoul, pollute, defile, make filthy”) (compare also Middle English filen (“to make foul, impure, or unclean, pollute; pollute morally or spiritually; desecrate, profane; have sexual intercourse with; rape; etc.”)) and foulen (“to make dirty, pollute; become dirty; defecate; deface or deform; pollute morally or spiritually; damage, injure; destroy; treat unfairly, oppress; tread on, trample”). Filen and foulen are respectively from Old English fȳlan (“to befoul, defile, pollute”) and Old English fūlian (“to foul”), from Proto-West Germanic *fūlijan (“to make dirty, befoul”) and *fūlēn (“to become foul, decay”), both ultimately from Proto-Germanic *fūlaz (“dirty, foul; rotten”), from Proto-Indo-European *puH- (“foul; rotten”).
