I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">set ablaze</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 torch that I've seen before include "Source of light" , "Such a love song" , "Portable light; burn" , "may get one glowing" , "Set alight deliberately" .)
