Made further transgressions when told to abrogate (7)
I believe the answer is:
rescind
'abrogate' is the definition.
(I've seen this in another clue)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for rescind that I've seen before include "Revoke (order)" , "Cinders (anag.)" , "Discern in order to cancel, say a law" , "Annul using cinders" , "Withdraw (decree)" .)
