Unspecified object, no matter what (8)
I believe the answer is:
This clue is a double definition.
'unspecified object' is the first definition.
(I've seen this before)
'no matter what' is the second definition.
(both can mean any item)
(Other definitions for anything that I've seen before include ""Whatever!"" , "An unspecified item" , "Musical by 14" , "Unspecified object" , "Aught" .)
