I believe the answer is:
hoard
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">stash</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that stash can be written as hoard)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for hoard that I've seen before include "Accumulation" , "accumulated wealth" , "Stockpile" , "Valuable store" , "Squirrel away" .)
