Witch, from the Old English wiċċe, is a term rooted in European folklore and superstition for a practitioner of witchcraft, magic or sorcery. Traditionally associated with malevolent magic, with those accused of witchcraft being the target of witch-hunts, in the modern era the term has taken on different meanings. In literature, a 'witch' can now simply refer to an alluring women capable of 'bewitching' others. In neopagan religions such as Wicca the term has meanwhile been adopted as the female term for an adherent.

A warlock is a male practitioner of witchcraft.
