Country, nation (5)
I believe the answer is:
state
I believe this clue is a double definition.
'country' is the first definition.
(I know that country can be written as state)
'nation' is the second definition.
(I know that nation can be written as state)
(Other definitions for state that I've seen before include "eg Rhode Island" , "See 3" , "Georgia < or Virginia" , "Declare; affirm" , "For example, New York or Washington but not Boston or Philadelphia" .)
