Chaps in his punt adrift, needing correction (10)
I believe the answer is:
punishment
'correction' is the definition.
(thesaurus)
'chaps in his punt adrift' is the wordplay.
'chaps' becomes 'men' (I've seen this before).
'in' means one lot of letters goes inside another.
'adrift' is an anagram indicator.
'his'+'punt'='hispunt'
'hispunt' is an anagram of 'punisht'.
'men' put within 'punisht' is 'PUNISHMENT'.
'needing' is the link.
(Other definitions for punishment that I've seen before include "See 6" , "Penalty" , "That may be fine" , "Beating" , "Discipline" .)
