<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">unspoken but understood</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 tacit that I've seen before include "Implied without being put into words" , "Understood without being directly expressed" , "Silent - understood" , "without speaking" , "Implied without being said" .)
