Polynesian island nation (5)
I believe the answer is:
samoa
'polynesian island nation' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for samoa that I've seen before include "Polynesian island group" , "Pacific island nation, capital Apia" , "Southwest Pacific island group" , "SW Pacific island chain" , "Polynesian isle" .)
