Witches
A Witch is a person who has the power to effect change by magical means ("witchcraft"). Keeping with historical usage, "Supernatural" seems to reserve the term "witch" for practitioners of black magic. Witches receive their power from Demons - presumably in exchange for their souls. It is notable that Sam, Dean, and Bobby often use the same spells and rituals, but would not consider themselves witches.
