<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">orphan</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for waif that I've seen before include "poor child" , "neglected issue" , "Neglected or orphaned child" , "Orphan" , "Gamin" .)
