Islander I see captured by Italian artist (8)
I believe the answer is:
tahitian
'islander' is the definition.
(someone from Tahiti)
'i see captured by italian artist' is the wordplay.
'i see' becomes 'ah' ('ah' can be used to express understanding).
'captured by' means one lot of letters goes inside another.
'italian artist' becomes 'titian' (I've seen this before).
'ah' inserted inside 'titian' is 'TAHITIAN'.
(Other definitions for tahitian that I've seen before include "It, in a hat (anag)" , "Citizen of Papeete, say" , "someone on tropic island" , "South Sea islander" , "Polynesian islander" .)
