I believe the answer is:
sticky
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">gummy</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that gummy can be written as sticky)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for sticky that I've seen before include "Damp with sweat" , "Adhesive; awkward" , "Gluey, gooey" , "Close" , "Adhesive - muggy" .)
