Board agreed in two European languages (5)

I believe the answer is:

ouija

I'm a little stuck... Click here to teach me more about this clue!

'board' is the definition.
(I know that Ouija is a type of board)

I don't understand the rest of the clue.

(Other definitions for ouija that I've seen before include "Board for contacting spirits" , "This board is used in spiritualism" , "Board sometimes used at seances" , "Occult board" , "This board is used in spiritualist proceedings" .)

I've seen this clue in The Telegraph.
