Hit hard getting boxing prize (4)
I believe the answer is:
belt
This clue is a double definition.
'hit hard' is the first definition.
(I've seen this in another clue)
'boxing prize' is the second definition.
(I've seen this in another clue)
'getting' acts as a link.
(Other definitions for belt that I've seen before include "Big hit" , "Article of clothing" , "sock or > tie" , "Token of judo rank" , "See 18" .)
