Article or item (5)
I believe the answer is:
thing
I believe this is a double definition.
'article' is the first definition.
(both can mean an object)
'item' is the second definition.
(both can mean an object)
(Other definitions for thing that I've seen before include "cup of tea" , "An unnamed object or item" , "See 1" , "Article" , "Inanimate object" .)
