Etymology

Probably from Latin mania. Alternatively from Proto-Indo-European *mei 'to change, exchange'. Compare Sanskrit मेनि ‎(mení, “revenge, vengeance”), Avestan [script needed] ‎(maēni, “punishment”), Old High German mein ‎(“incorrect, deceitful”), Old Norse meinn ‎(“harmful”), mein ‎(“damage, pity, misfortune”).
