English Literature First for snob (7)
I believe the answer is:
elitist
'snob' is the definition.
(thesaurus)
'english literature first' is the wordplay.
'english' becomes 'e' (abbreviation).
'literature' becomes 'lit'.
'first' becomes 'ist'.
'e'+'lit'+'ist'='ELITIST'
'for' acts as a link.
(Other definitions for elitist that I've seen before include "Exclusive type" , "Looking down on others" , "One who feels superior" , "Favouring a chosen few" , "One without the common touch" .)
