Sinful lady to abandon sin (3-5)
I believe the answer is:
she-devil
'sinful lady' is the definition.
'abandon sin' is the wordplay.
'abandon' becomes 'shed' (I've seen this before).
'sin' becomes 'evil' (I've seen this before).
'shed'+'evil'='SHE-DEVIL'
'to' is the link.
(Other definitions for she-devil that I've seen before include "Malicious and spiteful woman" , "woman like Lilith" .)
