Yeah, I'm a warlock.
You got a problem with that?
“Witch,” though a gender-neutral term, is female first. So it's convenient to have a term that specifies: male of the species.
Interestingly, it's a Scots word in origin. (In Sassenach they say warlowe.) Maybe they had more problems with male witches North of the Border.
That's not surprising. Throughout the Norse culture sphere, the majority of witches have always been men. Most executed witches in Scandinavia were male.
No, I'm not a wizard, but that's a class difference. Wizards are gentry. Warlockry is for us yeomen.
Some Wiccans are allergic to the term. Since the number of men in Wicca has been waning away for years, maybe it's moot. But in Old Craft—where men still constitute a numerical majority—most of us are fine with “warlock.”
And no one denies that it's a word of power.
Some object on the grounds that it means “oath-breaker.”
Well, they're wrong.
