I believe the answer is:
owner
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">possessor</span>' is the definition.<br/ ><span class="explanation-format__explanation">(synonyms)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for owner that I've seen before include "Keeper" , "Holder, possessor" , "The person in legal possession" , "Title-holder" , "Legal possessor" .)
