<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">noble lady</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for duchess that I've seen before include "Great lady" , "title" , "Noble lady" , "Titled female" , "Titled lady" .)
