Haughty one (4)
I believe the answer is:
snob
'haughty one' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for snob that I've seen before include "One despising inferiors" , "Snooty type" , "One who considers himself socially superior" , "One has pretensions" , "High-minded type" .)
