Chides (6)
I believe the answer is:
scolds
'chides' is the definition.
('scold' can be a synonym of 'chide')
This is the entire clue.
(Other definitions for scolds that I've seen before include "Censures, berates" , "Reprimands, tells off harshly" , "Dresses down" , "Berates, reproves" , "Chides, reprimands" .)
