Smacks on the wrist? (5)
I believe the answer is:
cuffs
This clue could be a double definition.
'smacks' is the first definition.
'the wrist' is the second definition.
I know that 'wrist' relates to this answer. I also know that both the answer and definition are singular nouns
'on' is the link.
Can you help me to learn more?
(Other definitions for cuffs that I've seen before include "Strikes with an open hand" , "Ends of sleeves" , "Open-handed blows" , "Sleeve-ends" , "Hits" .)
