<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">board of inquiry?</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for ouija that I've seen before include "(Seance) lettered board" , "Type of board used in seances" , "Occult board" , "This board is used in spiritualism" , "Board able to answer questions?" .)
