Turn back to scold about (6)
I believe the answer is:
rotate
'turn' is the definition.
(rotating is a kind of turning)
'back to scold about' is the wordplay.
'back' says the letters should be written backwards.
'scold' becomes 'rate' (I've seen this before).
'about' indicates putting letters inside.
'to' backwards is 'ot'.
'ot' inserted inside 'rate' is 'ROTATE'.
(Other definitions for rotate that I've seen before include "Spin as on axle" , "Whisk round" , "wheel" , "Turn round" , "Pivot" .)
