One maybe taking Jersey leader around street (7)
I believe the answer is:
rustler
'one maybe taking jersey' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'leader around street' is the wordplay.
'leader' becomes 'ruler' (I've seen this before).
'around' indicates putting letters inside.
'street' becomes 'st' (abbreviation).
'ruler' going around 'st' is 'RUSTLER'.
Can you help me to learn more?
(Other definitions for rustler that I've seen before include "One who takes livestock" , "Cattle stealer" , "Livestock thief" , "lawbreaker" , "Stock taker?" .)
