I believe the answer is:
rani
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">raja's wife</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for rani that I've seen before include "Raja's queen" , "Hindu queen or princess" , "Member of royal family" , "Royal Indian female" , "Indian princess" .)
