South Pacific island (6)
I believe the answer is:
tahiti
'south pacific island' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for tahiti that I've seen before include "South Pacific island, linked to Paul Gauguin and Robert Louis Stevenson" , "I hit at the tropical island" , "Pacific island, Gauguin's home in the 1890s" , "I hit at this exotic island" , "Pacific island, the largest in French Polynesia" .)
