Transgression produces resentment (7)
I believe the answer is:
offence
I believe this is a double definition.
'transgression' is the first definition.
(I know that offence is a type of transgression)
'resentment' is the second definition.
(I've seen this before)
'produces' is the link.
(Other definitions for offence that I've seen before include "Attack - crime" , "An illegal act, cause of annoyance" , "Discourtesy" , "Aggressive action" , "The action of attacking an enemy" .)
