I believe the answer is:
unfurl
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">unroll</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that unroll can be written as unfurl)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for unfurl that I've seen before include "Open (e.g. brolly)" , "Allow (flag) to fly" , "Open (a rolled umbrella)" , "Open out like flag" , "Spread out as with flag" .)
