Marriage partner (6)
I believe the answer is:
spouse
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">marriage partner</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 spouse that I've seen before include "Possibly wife" , "Elizabethan dance" , "Very hot and dry" , "Consort" , "Married partner" .)
