Country inn with a great spread (9)
I believe the answer is:
argentina
'country' is the definition.
(Argentina is an example)
'inn with a great spread' is the wordplay.
'with' says to put letters next to each other.
'spread' indicates anagramming the letters.
'inn'+'a'+'great'='innagreat'
'innagreat' with letters rearranged gives 'ARGENTINA'.
(Other definitions for argentina that I've seen before include "An ingrate in S American country" , "part of 18 [SOUTH AMERICA]" , "Republic" , "Ta, Grannie, for the odd country" , "Song from 'Evita' - 'Don't Cry For Me . . . . . . . . . '" .)
