Condescending manner (4)
I believe the answer is:
airs
'condescending manner' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for airs that I've seen before include "Arrogance" , "Ventilates or tunes" , "Broadcasts" , "Tunes and posturings" , "Attitudes or tunes" .)
