Etymology

Origin of pervert

First recorded in 1300–50; (for the verb) Middle English perverten, from Latin pervertere “to overturn, subvert,” from per- per- + vertere “to turn”; (for the noun) noun use of obsolete pervert “perverted”


Explanation

To pervert something is to corrupt it. For example, you could "pervert the course of justice" by lying on the witness stand. Another common use of pervert is as a word for a person who is sexually deviant; however, people also use this word more loosely to describe anyone who seems creepy. Perverting also means changing or subverting something. A cop who breaks the law is perverting the law. A criminal who convinces other people to become criminals is perverting them. So when you think of pervert, think change — change for the worse.
