I believe the answer is:

scold

I'm a little stuck... Click here to teach me more about this clue!

'rebuke' is the definition.
(I know that rebuke can be written as scold)

I don't understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for scold that I've seen before include "Upbraid" , "Chide - fishwife" , "Chide or reprimand" , "Chide, rebuke" , "Censure, berate" .)

I've seen this clue in the Sydney Morning Herald.
