I believe the answer is:
divorce
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">end of a marriage</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 divorce that I've seen before include "Legal end to a marriage" , "Split" , "Part" , "Get separated" , "Ending of marriage" .)
