Advisory board where some participants are late? (5)
I believe the answer is:
ouija
'advisory board' is the definition.
'Ouija' can be an answer for 'board' (Ouija board is an example). I'm not certain of the 'advisory' bit.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for ouija that I've seen before include "Type of board used in seances" , "Board sometimes used at seances" , "This board is used in spiritualistic sessions" , "Board used in spiritualist session" , "Medium's medium?" .)
