From Middle English wicked, wikked, an alteration of Middle English wicke, wikke (“morally perverse, evil, wicked”). Of uncertain origin. Possibly from an adjectival use of Old English wiċċa (“wizard, sorcerer”), from Proto-West Germanic *wikkō (“necromancer, sorcerer”), though the phonology makes this theory difficult to explain. Alternatively, perhaps related to English wicker, Old Norse víkja (“to bend to, yield, turn, move”), Swedish vika (“to bend, fold, give way to”), English weak.

Evil or mischievous by nature. Synonyms: evil, immoral, malevolent, malicious, nefarious, twisted, villainous; see also Thesaurus:evil
