<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">execrable</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for atrocious that I've seen before include "Extremely bad" , "Appallingly bad" , "Dreadful" , "Horrifyingly wicked" , "Foolish" .)
