Briefly show murderer turned evil (8)
I believe the answer is:
demoniac
'evil' is the definition.
Both the definition and answer are adjectives. Perhaps they are linked in a way I don't understand?
'briefly show murderer turned' is the wordplay.
'briefly show' becomes 'demo' (I've seen this in another clue. I am not sure about the 'briefly' bit.).
'murderer' becomes 'cain' (Cain who killed Abel).
'turned' shows that the letters should be reversed in order.
'cain' in reverse letter order is 'niac'.
'demo'+'niac'='DEMONIAC'
Can you help me to learn more?
(Other definitions for demoniac that I've seen before include "one that's potentially evil" , "Person possessed by an evil spirit" , "Diabolical" , "Comedian of frenzied sort" , "Comedian of devilish sort 98)" .)
