Cancels the law about bell-ringing (7)
I believe the answer is:
repeals
'cancels' is the definition.
(repealing is a kind of cancelling)
'law about bell-ringing' is the wordplay.
'law' becomes 'res' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'about' is an insertion indicator.
'bell ringing' becomes 'peal' (I've seen this in another clue).
'res' going around 'peal' is 'REPEALS'.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for repeals that I've seen before include "Annuls an act" , "Sets aside" .)
