I believe the answer is:
husband
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">male spouse</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 husband that I've seen before include "Use economically - partner" , "Partner in marriage" , "Better half's other half?" , "Use resources economically" , "Economically manage" .)
