The modern use of the term was introduced first as Wica in Gerald Gardner's Witchcraft Today (1954), as a collective noun ("the Wica") allegedly used as a self-designation by practitioners of witchcraft who initiated him in 1939. The spelling Wicca, again as a collective noun, is first attested in a letter to Gardner from his friend Margaret Bruce, dated 23 February 1960.
