Air lies about Middle Easterner (7)
I believe the answer is:
israeli
'middle easterner' is the definition.
(I've seen this before)
'air lies about' is the wordplay.
'about' indicates anagramming the letters.
'air'+'lies'='airlies'
'airlies' with letters rearranged gives 'ISRAELI'.
(Other definitions for israeli that I've seen before include "Levantine" , "Citizen of Middle Eastern state" , "Citizen of a country 'born' in 1948" , "One from Tel Aviv, perhaps" , "Nationality of citizen of Tel Aviv" .)
