I believe the answer is:
lid
<span class="explanation-format__ClueExplanation">I believe this is a double definition.<br/ ><br/ >'<span class="explanation-format__original">cover</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(lid is a kind of cover)</span><br/ ><br/ >'<span class="explanation-format__original">cap</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(eg the lid of a bottle)</span><br/ ><br/ ></span>
(Other definitions for lid that I've seen before include "Pie crust; cover" , "Cover for box or pot" , "Bottle or jar top" , "Kind of cover, may be hinged" , "Top or cover" .)
