Chaps on the punt will get bit of tuition for it (10)
I believe the answer is:
betterment
'it' is the definition.
The definition suggests a singular noun which matches the answer.
'chaps on the punt will get bit of tuition' is the wordplay.
'chaps' becomes 'men' (chap means a man).
'on' means one lot of letters go next to another.
'the punt will' becomes 'better' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'get bit of' suggests taking the first letters (just the first 'bit').
The initial letter of 'tuition' is 't'.
'men' after 'better' is 'bettermen'.
'bettermen'+'t'='BETTERMENT'
'for' is the link.
Can you help me to learn more?
(Other definitions for betterment that I've seen before include "Reform" , "improved condition" , "Improvement" , "Amelioration" , "advance" .)
