Snooty sort (4)
I believe the answer is:
snob
'snooty sort' is the definition.
(snob can mean a snooty person)
This is the entire clue.
(Other definitions for snob that I've seen before include "Snooty type" , "High-minded type" , "One for whom social status matters" , "Toffee-nose" , "One who considers himself socially superior" .)
