Imposing corporal punishment (8)
I believe the answer is:
striking
This could be a double definition.
'imposing' is the first definition.
(thesaurus)
'corporal punishment' is the second definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe you can see an association between them that I don't see?
Can you help me to learn more?
(Other definitions for striking that I've seen before include "Signal" , "Impressive; refusing to work" , "Hitting or refusing to work" , "Noticeable" , "Attracting attention by reason of being unusual" .)
