Attribute, feature (8)
I believe the answer is:
property
I believe this is a double definition.
'attribute' is the first definition.
(I know that property is a type of attribute)
'feature' is the second definition.
(thesaurus)
(Other definitions for property that I've seen before include "Quality; building" , "Real estate" , "Tangible possession" , "Attribute; chattel" , "Stuff that is owned" .)
