I believe the answer is:
copse
<span class="explanation-format__ClueExplanation">I believe this is a double definition.<br/ ><br/ >'<span class="explanation-format__original">wood</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(a copse is a small wood)</span><br/ ><br/ >'<span class="explanation-format__original">thicket</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(I know that thicket can be written as copse)</span><br/ ><br/ ></span>
(Other definitions for copse that I've seen before include "spinney" , "Dense thicket of trees" , "Scope for a small wood" , "Small thicket" , "A little wood" .)
