What's the equivalent of 'witches' for men? He-witches?
Anton, a male witch is a witch. No genders needed. There are there types, white gray and black and green. Actually there are many types, but that is a start.
Q. Are Witches only women?
A. No, although women do seem to predominate in the Craft overall. In fact, some traditions have only women practitioners, just as others have only men. A male Witch is simply called a Witch, never a warlock and it is considered an insult to call a male Witch "Warlock". The word "Warlock" actually means "oath breaker". Some traditions of Wicca separate between female/male. The word "Wicce" pronounced (Wik-kay) designates a female Witch and "Wicca" pronounced (Wik-kah) designates a male Witch.
