I believe the answer is:
bachelor
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">single man</span>' is the definition.<br/ ><span class="explanation-format__explanation">(unmarried man)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for bachelor that I've seen before include "he has no ties" , "leading man at start of Wedding Cantata" , "Non-married male" , "He's not married" , "Unmarried male" .)
