nay
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">a vote against</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for nay that I've seen before include "In point of fact - a parliamentary vote against" , "Indeed" , "Negative response" , "No (dialect); or rather" , "No - a negative vote" .)
