Turn performing in front of an audience in Wicked (4)
I believe the answer is:
evil
'wicked' is the definition.
(associated in meaning)
'turn performing' is the wordplay.
'turn' shows that the letters should be reversed in order.
'performing' becomes 'live' (I've seen this in another clue).
'live' reversed gives 'EVIL'.
'in front of an audience in' acts as a link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for evil that I've seen before include "heinous" , "Demonic" , "Live badly in depravity" , "mischief" , "Morally reprehensible" .)
