Enthusiast should have fun with edgy entertainer (7)
I believe the answer is:
enjoyer
'enthusiast should' is the definition.
I can't judge whether this defines the answer.
'have fun with edgy entertainer' is the wordplay.
'have fun with' becomes 'enjoy' (I've seen this in another clue).
'edgy entertainer' becomes 'er' (I am not sure about this - if you are sure you should believe this answer much more).
'enjoy'+'er'='ENJOYER'
Can you help me to learn more?
(Another definition for enjoyer that I've seen is " One getting pleasure".)
