I believe the answer is:
nod
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">silent approval</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 nod that I've seen before include "positive sign" , "slight bow" , "The Land of ... lay east of Eden" , "overlook something" , "Gesture; agree" .)
