Witch

The definition of a Witch was never confirmed within the series, but it is generally believed to be a gender-specific term for a female sorcerer. It is usually used in reference to sorceresses with sinister motives, or who used dark magic to achieve their aims.

Morgana Pendragon was one such sorceress. She sought revenge against Uther and Arthur Pendragon for their hatred of magic and repeatedly tried to seize the throne of Camelot. Her half-sister Morgause also sought revenge against Uther, as did the High Priestess Nimueh.

However, there were also many witches who sought to use their magic for good. Gaius's former fiancée Alice, for example, was highly skilled at healing magic (Love in the Time of Dragons).
