<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">more's the pity</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for alas that I've seen before include "Sad to say!" , "Proper, respectable" , "Expression of grief/pity" , "Expression of grief or misfortune" , "woebegone expression" .)
