Sermon is so crude getting broadcast (9)
I believe the answer is:
discourse
'sermon' is the definition.
('discourse' can be a synonym of 'sermon')
'is so crude getting broadcast' is the wordplay.
'getting' means one lot of letters go next to another.
'broadcast' indicates anagramming the letters.
'is'+'so'+'crude'='issocrude'
'issocrude' anagrammed gives 'DISCOURSE'.
(Other definitions for discourse that I've seen before include "Conversation, dialogue" , "Speech - conversation" , "verbal communication" , "Engage in conversation; debate" , "Written or spoken communication" .)
