I believe the answer is:
eve
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">adam's madam</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 eve that I've seen before include "Lady first appearing" , "She reportedly lived first" , "comes before Jan. 1st" , "Previous day" , "Girl" .)
