<span class="explanation-format__ClueExplanation">I believe this is a double definition.<br/ ><br/ >'<span class="explanation-format__original">recess</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(I know that alcove is a type of recess)</span><br/ ><br/ >'<span class="explanation-format__original">niche</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(alcove is a kind of niche)</span><br/ ><br/ ></span>
