Muscat resident (5)
I believe the answer is:
omani
'muscat resident' 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 "one from the Middle East" , "Native of one Arabian sultanate" , "Inhabitant of Middle Eastern sultanate" , "Naomi (anag) -- from Muscat?" , "Someone from Muscat" .)
