<span class="explanation-format__ClueExplanation">This clue is a double definition.<br/ ><br/ >'<span class="explanation-format__original">absent</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(I've seen this in other clues)</span><br/ ><br/ >'<span class="explanation-format__original">away</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(I know that away can be written as off)</span><br/ ><br/ ></span>
