Port and orange (5)
I believe the answer is:
jaffa
This clue is a double definition.
'port' is the first definition.
(I know that Jaffa is a port)
'orange' is the second definition.
(Jaffa orange is an example)
'and' acts as a link.
(Other definitions for jaffa that I've seen before include "Port near Tel Aviv" , "Brand of oranges (or cakes)" , "Orange from Israel" , "Ancient Israeli seaport, now part of Tel Aviv" , "Israeli town" .)
