I believe the answer is:
assent
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">go along</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 assent that I've seen before include "Give consent" , "Agreement or concurrence" , "Consent or approval" , "Okay" , "Acquiescence" .)
