Comedian makes hoodlum forget name (7)
I believe the answer is:
gagster
'comedian' is the definition.
(I've seen this in another clue)
'hoodlum forget name' is the wordplay.
I cannot quite see how this works, but
'name' could be 'ag' and 'ag' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
'makes' acts as a link.
Can you help me to learn more?
(Other definitions for gagster that I've seen before include "Comedian (one letter short of a criminal)" , "Joker" , "Who'll crack you up" , "comic" , "who makes jokes?" .)
