Transgression and bad character (6)
I believe the answer is:
sinbad
'character' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'transgression and bad' is the wordplay.
'transgression' becomes 'sin' (sin is a kind of transgression).
'and' is a charade indicator (letters next to each other).
'sin'+'bad'='SINBAD'
Can you help me to learn more?
(Other definitions for sinbad that I've seen before include "Legendary mariner noted for seven voyages" , "Sailor of Eastern tale" , "Arabian Nights sailor who made seven voyages" , "Pantomime sailor from the Arabian Nights (6)" , "Legendary sailor from Arabian nights" .)
