Spanish port I'm leaving without tatty garment on (9)
I believe the answer is:
tarragona
'spanish port' is the definition.
(I've seen this before)
'i'm leaving without tatty garment on' is the wordplay.
I cannot really see how this works, but
'on' is within the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for tarragona that I've seen before include "Spanish wine" , "port, in Spain" , "Spanish port" , "Spanish city" , "Spanish province" .)
