Banter from winger that’s not kept in check (5)
I believe the answer is:
chaff
'banter' is the definition.
('chaff' can be a synonym of 'banter')
'winger that's not kept in check' is the wordplay.
I cannot really understand how this works, but
'check' could be 'ch' (I've seen this in other clues) and 'ch' is located in the answer.
This explanation may well be incorrect...
'from' acts as a link.
(Other definitions for chaff that I've seen before include "shells" , "fodder" , "Husks - jokes" , "Worthless material (from corn)" , "Corn-husks separated from the grain" .)
