<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">silent votes</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for nods that I've seen before include "Non-verbal indications of assent" , "Affirmative gestures" , "Shows assent" , "Inclines head" , "Agrees" .)
