Object, item (5)
I believe the answer is:
thing
I believe this clue is a double definition.
'object' is the first definition.
(an object is a thing or item)
'item' is the second definition.
(both can mean an object)
(Other definitions for thing that I've seen before include "A creature" , "Individual object" , "Affair - matter" , "Object, artefact" , "An unnamed object or item" .)
