Shows manners (4)
I believe the answer is:
airs
I believe this is a double definition.
'shows' is the first definition.
(shows on TV)
'manners' is the second definition.
(air is a kind of manner)
(Other definitions for airs that I've seen before include "Ventilates, say grievances" , "Arrogance" , "Tunes and posturings" , "Melodies or artificial manners" , "- - and graces" .)
