It can be broken in Bulawayo (3)
I believe the answer is:
law
'it can be broken' is the definition.
The definition suggests a singular noun which matches the answer.
'in bulawayo' is the wordplay.
'in' says the answer is hidden in the clue.
'LAW' is hidden in the letters of 'bulawayo'.
Can you help me to learn more?
(Other definitions for law that I've seen before include "Rule prohibiting certain actions" , "Collection of rules for a society" , "Set of rules laid down by authority" , "Edict" , "Body of rules of conduct for a society" .)
