Female no wife for Saudi neighbour (4)
I believe the answer is:
oman
'wife for saudi neighbour' is the definition.
I can't judge whether this defines the answer.
'female no' is the wordplay.
'female' becomes 'oma' (I can't explain this - if you can you should give a lot more credence to this answer).
'no' becomes 'n' (common abbreviation).
'oma'+'n'='OMAN'
Can you help me to learn more?
(Other definitions for oman that I've seen before include "Gulf state" , "Middle Eastern country" , "Gulf sultanate" , "monarchy" , "Sultanate in southwest Asia" .)
