nonsense verse

I'm a little stuck... Click here to teach me more about this clue!

'lear production?' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps there's a link between them I don't understand?

'bad son's even seen entertaining king' is the wordplay.
'bad' is an anagram indicator.
'entertaining' is an insertion indicator.
'king' becomes 'R' (abbreviation for rex, king in Latin).
'sons'+'even'+'seen'='sonsevenseen'
'sonsevenseen' with letters rearranged gives 'nonsensevese'.
'nonsensevese' enclosing 'r' is 'NONSENSE VERSE'.
