Agreeable reply (3)
I believe the answer is:
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">agreeable reply</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 yes that I've seen before include "Positive response" , "Positive reply" , "Yea" , "Affirmative reply" , "Indeed" .)
