Spanish city; orange variety (8)
I believe the answer is:
valencia
I believe this is a double definition.
'spanish city' is the first definition.
(I've seen this before)
'orange variety' is the second definition.
(I've seen this in another clue)
(Other definitions for valencia that I've seen before include "somewhere in Spain)" , "Spanish city and region" , "city in Spain?" , "port in the Med" , "European area" .)
