Port served in a speakeasy? (4)
I believe the answer is:
aden
'port' is the definition.
(port in Yemen)
'in a speakeasy?' is the wordplay.
'in' means one lot of letters goes inside another.
'a' becomes 'an'.
'speakeasy?' becomes 'de' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'an' placed around 'de' is 'ADEN'.
'served' acts as a link.
Can you help me to learn more?
(Other definitions for aden that I've seen before include "Dean is in the Yemen, strangely" , "Red Sea port" , "Dane in seaport of Yemen" , "Main port of Yemen" , "somewhere on the Arabian peninsula" .)
