<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">suffrage</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that suffrage can be written as vote)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for vote that I've seen before include "Take part in an election" , "Put one's cross" , "Indicate choice in an election" , "Ballot, exercise of franchise" , "Cast a ballot" .)
