Eastern country without a prominent feature (4)
I believe the answer is:
chin
'prominent feature' is the definition.
(facial feature)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for chin that I've seen before include "Feature of face" , "Point of the jaw" , "Part of the face (on which one may have to take it?)" , "hit" , "Lower face part" .)
