Punish or correct (10)
I believe the answer is:
discipline
I believe this is a double definition.
'punish' is the first definition.
(disciplining is a kind of punishing)
'correct' is the second definition.
(I know that correct can be written as discipline)
(Other definitions for discipline that I've seen before include "Field" , "Training designed to engender self-control" , "Correct" , "Branch of knowledge; punish" , "Correction" .)
