^^That's a translated Slavic loanword that only has any currency owing to a certain recently popular fantasy franchise ya know. And I'll be mighty surprised if that isn't exactly what 99% of English-speakers think of when they hear the word, presuming they recognise it at all.
You're thinking of warlock - which doesn't really see much use outside Dungeons & Dragons which likes digging up more obscure words to use in classnames and whatnots (see also the sharp distinction it draws between the factually interchangeable terms "wizard" and "sorcerer").
