I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">unfurl</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that unfurl can be written as unroll)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for unroll that I've seen before include "Unfurl" , "Reverse winding or twisting" , "Open out (eg, scroll)" , "Dismantle the joint, perhaps" , "Gradually reveal" .)
