Addressing a dressing down (7,2)
I believe the answer is:
talking to
'addressing' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for talking to that I've seen before include "Reproof" , "carpeting" , "sharp rebuke" , "What lecture might be" , "Earful" .)
