In darkness (5)
I believe the answer is:
unlit
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">in darkness</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for unlit that I've seen before include "Lacking illumination" , "With no lighting" , "such as dark alley?" , "Without illumination" , "Not yet burning" .)
