Is able to get point of punishment (4)
I believe the answer is:
cane
'punishment' is the definition.
(I've seen this in other clues)
'is able to get point' is the wordplay.
'is able to' becomes 'can' (if you can do something you are able to do it).
'get' is a charade indicator (letters next to each other).
'point' becomes 'e' (compass point).
'can'+'e'='CANE'
'of' acts as a link.
(Other definitions for cane that I've seen before include "e.g. Bamboo stem" , "Beat; sugar producer" , "Stem of palm" , "A slender wooden rod for weaving" , "African country formerly called Gold Coast" .)
