Board making a late communication (5)
I believe the answer is:
ouija
'board' is the definition.
(Ouija is an example)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for ouija that I've seen before include "This board is used in spiritualist proceedings" , "Board able to answer questions?" , "(Seance) lettered board" , "This board is used in spiritualism" , "Board for contacting spirits" .)
