Plays on the radio (4)
I believe the answer is:
airs
'plays on the radio' 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 "'Tunes, melodies (4)'" , "Tunes and affectations" , "Broadcasts" , "affectation of superiority" , "Melodies or artificial manners" .)
