What will gunman do to give punishment? (8)
I believe the answer is:
hellfire
'punishment?' is the definition.
(I have seen 'Eternal punishment' mean 'hellfire' so perhaps 'punishment' could also mean 'hellfire')
'what will gunman do' is the wordplay.
I cannot quite see how this works, but
'will' could be 'll' (contracted form, as in 'he'll' - 'he will') and 'll' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
'to give' is the link.
Can you help me to learn more?
(Other definitions for hellfire that I've seen before include "endless torment" , "worst possible punishment" , "Infernal flames" , "Flames of damnation" , "Punishment in a very hot place" .)
