Yes, in France and Germany, this board can communicate with the dead (5)
I believe the answer is:
ouija
'this board can communicate with the dead' is the definition.
'ouija' can be an answer for 'board' (Ouija is an example). I'm not certain of the remainder of the definition.
'yes in france and germany' is the wordplay.
'yes in france' becomes 'oui' (I've seen this in another clue).
'and' says to put letters next to each other.
'germany' becomes 'ja' (I am not sure about this - if you are sure you should believe this answer much more).
'oui'+'ja'='OUIJA'
Can you help me to learn more?
(Other definitions for ouija that I've seen before include "(Seance) lettered board" , "Kind of board used in seances" , "This board is used in spiritualist proceedings" , "This board is used in spiritualistic sessions" , "Board able to answer questions?" .)
