<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">no aristocrat</span>' is the definition.<br/ ><span class="explanation-format__explanation">(ordinary person as opposed to an aristocrat)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for commoner that I've seen before include "Not a nobleman" , "A non-aristocrat" , "He's not a member of the nobility" , "certain type of undergraduate" , "One not of noble rank" .)
