I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">possessors</span>' is the definition.<br/ ><span class="explanation-format__explanation">('owner' can be a synonym of 'possessor')</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for owners that I've seen before include "Those in lawful possession, as of house" , "Worsen for possessors" , "Proprietors" , "Legal possessors" , "Holders, possessors" .)
