I believe the answer is:

<span class="explanation-format__ClueExplanation">I believe this is a double definition.<br/ ><br/ >'<span class="explanation-format__original">attribute</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(I know that property is a type of attribute)</span><br/ ><br/ >'<span class="explanation-format__original">feature</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(thesaurus)</span><br/ ><br/ ></span>
(Other definitions for property that I've seen before include "Quality; building" , "Real estate" , "Tangible possession" , "Attribute; chattel" , "Stuff that is owned" .)
