Forgive scam, being tricked (7)
I believe the answer is:
condone
'forgive' is the definition.
(I know that condone is a more specific form of forgive)
'scam being tricked' is the wordplay.
'scam' becomes 'con' (both can mean a fraudulent scheme).
'being tricked' becomes 'done' (I've seen this before).
'con'+'done'='CONDONE'
(Other definitions for condone that I've seen before include "Overlook - forgive" , "Accept or forgive (bad behaviour)" , "Excuse made" , "Forgive, sanction" , "Accept (wrong behaviour)" .)
