I believe the answer is:
peace
<span class="explanation-format__ClueExplanation">I believe this is a double definition.<br/ ><br/ >'<span class="explanation-format__original">calm</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(peaceful situation)</span><br/ ><br/ >'<span class="explanation-format__original">quietness</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(I know that peace is a type of quietness)</span><br/ ><br/ ></span>
