Looks down on (6)
I believe the answer is:
scorns
'looks down on' is the definition.
('scorn' can be a synonym of 'look down on')
This is the entire clue.
(Other definitions for scorns that I've seen before include "Despises, has contempt for" , "Derides or desises" , "Has or shows contempt for" , "Has contempt for, disdains" , "Rejects with contempt" .)
