I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">more sage</span>' is the definition.<br/ ><span class="explanation-format__explanation">('wise' can be similar in meaning to 'sage')</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for wiser that I've seen before include "A little more sage" , "more like Charles V" , "Less foolish" , "more enlightened" , "More shrewd" .)
