Why deliver a reprimand? (4,3)
I believe the answer is:
what for
I believe this clue is a double definition.
'why' is the first definition.
(thesaurus)
'a reprimand?' is the second definition.
(what for is a kind of reprimand)
'deliver' is the link.
(Other definitions for what for that I've seen before include "Beating" , "reprimand?" , "it's a question of purpose" , "Punishment that may be given" .)
