Society shunned by NE European scholar (7)
I believe the answer is:
etonian
'scholar' is the definition.
(graduate of Eton College)
'society shunned by ne european' is the wordplay.
'society' becomes 's' (common abbreviation in names of organisations).
'shunned by' indicates named letters should be taken away.
'ne european' becomes 'Estonian' (from Estonia).
'estonian' with 's' removed is 'ETONIAN'.
(Other definitions for etonian that I've seen before include "Relating to one particular school" , "One educated at famous public school" , "student in establishment?" , "Public school kid" , "Alumnus of famous English school" .)
