Islands off Portugal (6)
I believe the answer is:
azores
'islands off portugal' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for azores that I've seen before include "Atlantic islands belonging to Portugal" , "Group of Portuguese volcanic islands in N Atlantic" , "Portuguese archipelago" , "As zero (anag)" , "Portuguese islands in the North Atlantic" .)
