Country nut (6)
I believe the answer is:
brazil
I believe this is a double definition.
'country' is the first definition.
(Brazil is an example)
'nut' is the second definition.
(brazil is a kind of nut)
(Other definitions for brazil that I've seen before include "South American state" , "that may be shelled" , "Football World Cup holders" , "Largest South American country" , "Country Charley's Aunt came from" .)
