Lore confused character (4)
I believe the answer is:
role
'character' is the definition.
(synonyms)
'lore confused' is the wordplay.
'confused' indicates anagramming the letters.
'lore' anagrammed gives 'ROLE'.
(Other definitions for role that I've seen before include "Acting part" , "Playing part" , "Stage part" , "Function; part" , "Impersonation" .)
