Lore confused character (4)
I believe the answer is:
role
'character' is the definition.
('role' can be a synonym of 'character')
'lore confused' is the wordplay.
'confused' indicates an anagram.
'lore' with letters rearranged gives 'ROLE'.
(Other definitions for role that I've seen before include "Acting part" , "Playing part" , "Stage part" , "Function; part" , "Impersonation" .)
