I believe the answer is:
betrothed
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">engaged to be married</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 betrothed that I've seen before include "Engaged to be married" , "Spoken for" , "Promised in marriage" , "intended" , "committed somehow" .)
