One bearing stripes from such punishment? (8)
I believe the answer is:
corporal
'punishment?' is the definition.
(corporal punishment is a kind of punishment)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for corporal that I've seen before include "NCO rank below sergeant" , "Bodily" , "in the flesh" , "Army rank" , "One trained for engagement" .)
