Crazy person involved in a cult (7)
I believe the answer is:
lunatic
'crazy' is the definition.
(lunatic can mean crazy or mad)
'involved in a cult' is the wordplay.
'involved' indicates an anagram (involved can mean confusing or complex).
'in'+'a'+'cult'='inacult'
'inacult' with letters rearranged gives 'LUNATIC'.
'person' acts as a link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for lunatic that I've seen before include "bananas" , "Mad" , "Deranged" , "Madman - idiot" , "Insane person" .)
