Cowan(religion, spiritualism, and occult)
Term used by Witches for a non-Witch, someone who has not been initiated into the Old Religion. According to the Oxford English Dictionary, a cowan is "uninitiated, outside, profane," and that the term is slang for a sneak, or an inquisitive or prying person. In Scotland a cowan was someone uninitiated into the secrets of Freemasonry.
