I believe the answer is:
bottle
<span class="explanation-format__ClueExplanation">I believe this is a double definition.<br/ ><br/ >'<span class="explanation-format__original">courage</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(bottle can mean courage)</span><br/ ><br/ >'<span class="explanation-format__original">container</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(I know that bottle is a container)</span><br/ ><br/ ></span>
