An orange spot on the map (5)
I believe the answer is:
jaffa
'an orange' is the definition.
(Jaffa orange is an example)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for jaffa that I've seen before include "Port near Tel Aviv" , "ball of exceptional quality" , "Port in Israel" , "City in Israel" , "Ancient Israeli seaport, now part of Tel Aviv" .)
