Aden's country (5)
I believe the answer is:
yemen
'aden's country' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for yemen that I've seen before include "Saudi neighbour" , "Arabian republic, capital Sanaa" , "Republic sited on the SW corner of Arabia" , "Country to south of Saudi Arabia" , "Country between the Red Sea and the Gulf of Aden" .)
