Nectar ordered for islander (6)
I believe the answer is:
cretan
'islander' is the definition.
(someone from Crete)
'nectar ordered' is the wordplay.
'ordered' indicates an anagram.
'nectar' is an anagram of 'CRETAN'.
'for' acts as a link.
(Other definitions for cretan that I've seen before include "Greek islander" , "A Mediterranean islander" , "From Greece" , "Native of Greek island south of mainland (6)" , "Of a Greek island, centre of the Minoan civilisation" .)
