I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">cloud</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that cumulus is a type of cloud)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for cumulus that I've seen before include "A type wet inside" , "Type of cloud" , "Rounded kind of cloud" , "a fluffy wet type?" , "Sky coverage" .)
