One performing jokes about northern hoodlum (8)
I believe the answer is:
gangster
This might be a double definition.
'one performing jokes about northern' is the first definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'hoodlum' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for gangster that I've seen before include "Crook" , "Soprano possibly" , "Hoodlum" , "One of a group of violent criminals" , "Member of criminal mob" .)
