Lied over wicked person (8)
I believe the answer is:
evildoer
'person' is the definition.
(evildoer is a kind of person)
'lied over wicked' is the wordplay.
'wicked' indicates anagramming the letters.
'lied'+'over'='liedover'
'liedover' anagrammed gives 'EVILDOER'.
(Other definitions for evildoer that I've seen before include "Wicked person" , "One who commits very bad deeds" , "sinner" , "Over idle (anag) - villain" , "'baddie'?" .)
