Pretentious manner (4)
I believe the answer is:
airs
'pretentious manner' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for airs that I've seen before include "feelings" , "- - and graces" , "affected demeanour" , "affectation of superiority" , "Ventilates, say grievance" .)
