Ross

I believe the answer is:

nod

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">signal assent</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 "sign of approval" , "Affirmative action?" , "Incline the head" , "Signify assent" , "Bob the head" .)

I've seen this clue in The Telegraph and The Mirror.
