mumbling

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

'hard to understand this' is the definition.
The definition suggests a singular noun which matches the answer.

'mother with jewellery' is the wordplay.
'mother' becomes 'mum' (informal term for mother).
'with' says to put letters next to each other.
'jewellery' becomes 'bling' (informal term for jewellery).
'mum'+'bling'='MUMBLING'

Can you help me to learn more?
