State of one possessed coming back with nothing? (5)
I believe the answer is:
idaho
'state' is the definition.
(Idaho is an example)
'one possessed coming back with nothing?' is the wordplay.
'one' becomes 'i' (Roman numeral).
'possessed' becomes 'had' ('have' can be a synonym of 'possess').
'coming back' says the letters should be written backwards.
'with nothing?' becomes 'o' (I've seen this in other clues).
'had' reversed gives 'dah'.
'i'+'dah'+'o'='IDAHO'
'of' is the link.
(Other definitions for idaho that I've seen before include "The Gem State, known for its potatoes" , "The Gem State (US)" , "State of north-west USA" , "43rd US state" , "State of NW US" .)
