I believe the answer is:
add
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">find a total</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 add that I've seen before include "Total; put together" , "Put together - attach" , "Count up" , "Contribute" , "Include" .)
