perverso
/peɾˈbeɾso/ · B2 · adj
bad, mean, wicked
😈 perverso = per- (thoroughly) + verso (turned): thoroughly turned the wrong way
From Latin perversus, 'turned the wrong way', from per- (thoroughly) + vertere (to turn). Someone whose character has been turned away from what is right ends up bad, wicked, or perverted. English 'perverse' comes from the same root.
