A group of words said to indicate breaches of the peace (7)
I believe the answer is:
affrays
'breaches of the peace' is the definition.
The definition and answer can be both acts as well as being plural nouns.
Maybe you can see a link between them that I can't see?
'a group of words said to indicate' is the wordplay.
'a group of words' becomes 'phrase' (I've seen this in another clue).
'said' indicates a 'sounds like' (homophone) clue.
'to' means one lot of letters go next to another (I've seen this in other clues).
'indicate' becomes 'af' (I can't explain this - if you can you should give a lot more credence to this answer).
'phrase' is a homophone of 'frays'.
'frays' after 'af' is 'AFFRAYS'.
Can you help me to learn more?
(Other definitions for affrays that I've seen before include "Fights" , "Scraps" , "Noisy altercations" , "Altercations, disturbances" , "Brawls" .)
