Elitist society, very superior (6)
I believe the answer is:
snobby
'superior' is the definition.
(I've seen this before)
'elitist society very' is the wordplay.
'elitist' becomes 'snob' (I've seen this in another clue).
'society very' becomes 'by' (I can't justify this - if you can you should believe this answer much more).
'snob'+'by'='SNOBBY'
Can you help me to learn more?
(Other definitions for snobby that I've seen before include "superior" , "socially pretentious" , "Snooty, stuck-up" .)
