Arabian port (4)
I believe the answer is:
aden
'arabian port' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for aden that I've seen before include "foreign climes" , "Red Sea port" , "Dean is in the Yemen, strangely" , "Dean out in the seaport city" , "somewhere on the Arabian peninsula" .)
