Female suppressing Welsh nation (4)
I believe the answer is:
oman
'nation' is the definition.
(Oman is an example)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for oman that I've seen before include "Arabian country, capital Muscat" , "Gulf state" , "Nation" , "Arabian peninsula country" , "Former Gulf country, Muscat and --" .)
