Approval from two Europeans on board (5)
I believe the answer is:
ouija
This clue is a double definition.
'approval from two europeans' is the first definition.
('oui' and 'ja' are 'yes' in French and German)
'board' is the second definition.
(I know that Ouija is a type of board)
'on' acts as a link.
(Other definitions for ouija that I've seen before include "Board sometimes used at seances" , "Occult board" , "- Board may be used in a seance" , "Medium's medium?" , "Board able to answer questions?" .)
