Neighbor of a Yemeni (5)
I believe the answer is:
omani
'neighbor of a yemeni' 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 "Inhabitant of Middle Eastern sultanate" , "Middle East national" , "Speaker of Arabic" , "one from the Middle East" , "Eg, a native of Muscat" .)
