Neighbor of a Saudi (5)
I believe the answer is:
omani
'neighbor of a saudi' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for omani that I've seen before include "Naomi (anag) -- from Muscat?" , "Someone from Muscat" , "Native of one Arabian sultanate" , "one from the Middle East" , "coming from the Middle East" .)
