Arrogance of man averse to keeping uniforms apart (7)
I believe the answer is:
hauteur
'arrogance' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
(Other definitions for hauteur that I've seen before include "Overbearing arrogance" , "Nose-in-the-air pride" , "Proud disdain" , "Lofty pride, looking down on others" , "Proud superior attitude towards others" .)
