Parts for confused loser (5)
I believe the answer is:
roles
'parts' is the definition.
(parts in a play)
'confused loser' is the wordplay.
'confused' indicates anagramming the letters.
'loser' anagrammed gives 'ROLES'.
'for' acts as a link.
(Other definitions for roles that I've seen before include "Theatrical parts" , "Actors' parts" , "Dramatic parts" , "Parts in plays" , "Parts in a play" .)
