Spiritual board (5)
I believe the answer is:
ouija
'spiritual board' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ouija that I've seen before include "This board is used in spiritualism" , "Occult board" , "Kind of board used in seances" , "This board is used by spiritualists and seances" , "- Board may be used in a seance" .)
