Navigators' Islands, today (5)
I believe the answer is:
'navigators' islands today' 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 "Pacific islands state" , "Group of Polynesian 14s" , "Group of volcanic islands in the S Pacific" , "Pacific island nation, capital Apia" , "South Pacific island nation" .)
