Arab seen in Romania (5)
I believe the answer is:
omani
'arab' is the definition.
(Omani is an example)
'in romania' is the wordplay.
'in' indicates the answer is hidden within the clue.
'OMANI' can be found hidden inside 'romania'.
'seen' acts as a link.
(Other definitions for omani that I've seen before include "Middle Easterner" , "Inhabitant of Middle Eastern sultanate" , "Eg, a native of Muscat" , "From an Arabian country, capital Muscat" , "Gulf native" .)
