Take part in unpatriotic breach of the peace (4)
I believe the answer is:
riot
'the peace' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe there's an association between them I don't understand?
'take part in unpatriotic breach' is the wordplay.
'take part in' indicates the answer is hidden within the clue.
'RIOT' can be found hidden inside 'unpatriotic breach'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for riot that I've seen before include "scream" , "Affray, fighting in the streets" , "Wild disturbance by crowd of people" , "loose living" , "Disturbance by unruly mob" .)
