late 14c., perverten (transitive), "to turn someone aside from a right religious belief to a false or erroneous one; to distort natural order, misdirect misapply (justice, law, truth, etc.); to turn (something or someone) from right opinion or conduct," from Old French pervertir "pervert, undo, destroy" (12c.) and directly from Latin pervertere "overthrow, overturn," figuratively "to corrupt, subvert, abuse," literally "turn the wrong way, turn about," from per "away" (see per) + vertere "to turn, turn back, be turned; convert, transform, translate; be changed" (from PIE root *wer- (2) "to turn, bend").

pervert (n.)

1660s, "one who has forsaken a doctrine or system regarded as true, an apostate," from pervert (v.). The psychological sense of "one who has a perversion of the sexual instinct" is attested by 1897 (Havelock Ellis), originally especially of homosexuals, short for sexual pervert, which is attested by 1889.
