I believe the answer is:
closure
<span class="explanation-format__ClueExplanation">This clue is a double definition.<br/ ><br/ >'<span class="explanation-format__original">end</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(closuring is a kind of ending)</span><br/ ><br/ >'<span class="explanation-format__original">conclusion</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(closure is a kind of conclusion)</span><br/ ><br/ ></span>
