A great inn rebuilt in a South American country (9)
I believe the answer is:
argentina
'a south american country' is the definition.
(country in South America)
'a great inn rebuilt' is the wordplay.
'rebuilt' is an anagram indicator.
'great'+'inn'='greatinn'
'greatinn' with letters rearranged gives 'rgentina'.
'a'+'rgentina'='ARGENTINA'
'in' is the link.
(Other definitions for argentina that I've seen before include "Ta, Grannie, for the odd country" , "An ingrate in S American country" , "Home of the tango" , "Its capital Buenos Aires" , "Evita's country" .)
