City pro turned out to be islander (7)
I believe the answer is:
cypriot
'be islander' is the definition.
(I've seen this before)
'city pro turned out' is the wordplay.
'turned out' is an anagram indicator.
'city'+'pro'='citypro'
'citypro' anagrammed gives 'CYPRIOT'.
'to' acts as a link.
(Other definitions for cypriot that I've seen before include "One from Larnaca, say" , "Eg, a native of Nicosia" , "Mediterranean islander" , "One from Larnaka, say" , "One from Paphos, say" .)
