The name comes from Olde English.That is what I heard, as well. Even though it has been around for awhile, I am not sure where the term warlock originally came from, lol.
The spells of Wizards take into account the complexity of Nature and the Universe. A warlock is NOT a male witch. Many have fallen for this false definition which has hurt a lot of male witches who practice white magick. A warlock is an evil male witch who practices the diabolical dark arts. He is a traitor, a scoundrel, and liar.
