Favouring a select group (7)
I believe the answer is:
elitist
'favouring a select group' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for elitist that I've seen before include "Exclusive type" , "One who treats certain people as superior group" , "Favouring a chosen few" , "Favouring exclusivity" , "Snob" .)
