Fruit from Moroccan port (9)
I believe the answer is:
tangerine
'fruit from moroccan' is the definition.
'tangerine' can be an answer for 'moroccan' (I've seen this before). I am not sure about the 'fruit from' bit.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for tangerine that I've seen before include "Small orange" , "Moroccan" , "fruit product" , "orange colour" , "Small orange-like fruit (from North Africa?)" .)
