"The Cradle of Polynesia" (5)
I believe the answer is:
samoa
'the cradle of polynesia' 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 "South-west Pacific nation" , "Pacific islands state" , "Group of islands in the South Pacific" , "South Pacific island country, gaining its independence from New Zealand in 1962" , "Pacific island nation, capital Apia" .)
