To humiliate correctively will make Charlie speed up (7)
I believe the answer is:
chasten
'to humiliate correctively will' is the definition.
I can't tell whether this definition defines the answer.
'charlie speed up' is the wordplay.
'charlie' becomes 'C' (phonetic alphabet).
'speed up' becomes 'hasten' (I've seen this before).
'c'+'hasten'='CHASTEN'
'make' is the link.
Can you help me to learn more?
(Other definitions for chasten that I've seen before include "Censure severely" , "Moderate" , "Humble" , "Suppress" , "Subdue, correct by punishing" .)
