perverso
perverse
Origin: From Latin perversus, past participle of pervertere (to overturn, corrupt).
Also means
wicked
Usage Note
Perverso describes something morally corrupt, twisted, or producing the opposite of the intended result (effetto perverso = perverse effect, unintended harmful consequence). It is stronger than strano (strange) and carries a moral charge. The noun form is perversione (perversion). False friend warning: English 'perverse' can mean simply 'contrary', but Italian perverso leans more toward moral depravity.
Examples
"Quella politica ha avuto effetti perversi sull'economia."
Natural Translation
That policy had perverse effects on the economy.
