<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">hidden cache</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for hoard that I've seen before include "One's savings" , "Accumulate" , "A lot of people" , "Amass and store privately" , "Cache" .)
