Etymology and terminology
The most commonly accepted etymology derives warlock from the Old English ƿǣrloga, which meant "breaker of oaths" or "deceiver" and was given special application to the devil around 1000. In early modern Scots, the word came to be used as the male equivalent of witch (which can be male or female, but has historically been used predominantly for females). The term may have become associated in Scotland with male witches due to the idea that they had made pacts with Auld Hornie (the devil) and thus had betrayed the Christian faith and broke their baptismal vows or oaths. From this use, the word passed into Romantic literature and ultimately 20th-century popular culture. A derivation from the Old Norse varð-lokkur, "caller of spirits", has also been suggested, but the OED considers this implausible due to the extreme rarity of the Norse word and because forms without hard -k, which are consistent with the Old English etymology ("traitor"), are attested earlier than forms with a -k.

It is possible that it became associated with wizards and male witches in Scotland in the sense that someone who made a pact with Auld Hornie had betrayed the Christian faith and broken their baptismal vows. In that respect they were considered to be an 'oath breaker', a traitor and an enemy of the Church.
