Nectar befuddled Greek islander (6)
I believe the answer is:
cretan
'greek islander' is the definition.
(I've seen this before)
'nectar befuddled' is the wordplay.
'befuddled' is an anagram indicator.
'nectar' is an anagram of 'CRETAN'.
(Other definitions for cretan that I've seen before include "Native of a large Greek island" , "Greek islander" , "Native of Minoan island" , "One from largest Greek isle" , "Inhabitant of a large Greek island" .)
