Country accommodating a western nation (6)
I believe the answer is:
malawi
'nation' is the definition.
(Malawi is an example)
'country accommodating a western' is the wordplay.
'country' becomes 'mali' (Mali is an example**).
'accommodating' indicates putting letters inside.
'western' becomes 'w'.
'a'+'w'='aw'
'mali' enclosing 'aw' is 'MALAWI'.
(Other definitions for malawi that I've seen before include "Landlocked African country" , "East African country" , "African nation, formerly Nyasaland" , "Country in east central Africa" , "Country formerly known as Nyasaland" .)
