'long rambling pieces' is the definition.
The answer and definition can be both related to communication as well as being plural nouns.
Maybe they are linked in a way I don't understand?

'equip mother with stage parts' is the wordplay.
'equip' becomes 'rig' (rigging is a kind of equiping).
'mother' becomes 'ma' (Ma is another word for mother or mum).
'with' is a charade indicator (letters next to each other).
'stage parts' becomes 'roles' (I've seen this in another clue).
'rig'+'ma'+'roles'='RIGMAROLES'
