A place to hide port in Yemen (4)
I believe the answer is:
aden
'in yemen' is the definition.
(I know that Aden is a city)
'a place' is the wordplay.
'place' becomes 'den' (den is a kind of place).
'a'+'den'='ADEN'
'to hide port' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for aden that I've seen before include "Yemeni gulf" , "Dean is in the Yemen, strangely" , "Port city of Yemen" , "Commercial capital of Yemen" , "Dean is out in the Middle Eastern port" .)
