Peeress (4)
I believe the answer is:
lady
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">peeress</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that peeress can be written as Lady)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for lady that I've seen before include "See 7" , "Lord's partner" , "See 20" , "Lord's wife - peeress's title" , "Wife of gentleman" .)
