I believe the answer is:
their
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">belonging to those people</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for their that I've seen before include "Those people's" , "Relating to them" , "Belonging to him (perhaps wrongly)" , "Some would say his (or her)" , "belonging to an individual" .)
