<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">without a word</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 silently that I've seen before include "Without a word" , "Soundlessly" , "Mutely" , "Without a sound" , "Without making a noise" .)
