One with some scope for law enforcement (3)
I believe the answer is:
cop
'law enforcement' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'one with some scope' is the wordplay.
'one with' indicates the answer is hidden within the clue.
'COP' can be found hidden inside 'some scope'.
'for' is the link.
Can you help me to learn more?
(Other definitions for cop that I've seen before include "Police officer (slang)" , "Get" , "Policeman (slang)" , "An American policeman" , "Policeman (sl)" .)
