City of more notoriety (4)
I believe the answer is:
reno
'city' is the definition.
(city in Nevada)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for reno that I've seen before include "gambling centre" , "US gambling resort" , "City in Nevada known for casinos and easy divorces" , "Nevada city of Nero" , "Divorce capital of Nevada" .)
