A place to hide port in Yemen (4)
I believe the answer is:
aden
'port in yemen' is the definition.
(I've seen this in another clue)
'a place' is the wordplay.
'place' becomes 'den' (den is a kind of place).
'a'+'den'='ADEN'
'to hide' is the link.
This may not be correct. Some or all of it may be part of 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" .)
