Middle Eastern serial I translated (7)
I believe the answer is:
israeli
'middle eastern' is the definition.
(someone from Israel)
'serial i translated' is the wordplay.
'translated' indicates anagramming the letters.
'serial'+'i'='seriali'
'seriali' is an anagram of 'ISRAELI'.
(Other definitions for israeli that I've seen before include "countryman" , "from part of Middle East?" , "Country-dweller" , "From Jerusalem, perhaps" , "One from the Middle East" .)
