A good talking to (6)
I believe the answer is:
sermon
This clue might be a double definition.
'a good' is the first definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'talking to' is the second definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
Can you help me to learn more?
(Other definitions for sermon that I've seen before include "Moralising talk" , "Speech in church" , "Lesson or religious talk" , "Church address" , "Lecture in church" .)
