Confused noise with middle baby (6)
I believe the answer is:
hubbub
'confused noise' is the definition.
(I've seen this before)
'with middle baby' is the wordplay.
'with' says to put letters next to each other.
'middle' becomes 'hub' (hub is a kind of middle).
'baby' becomes 'bub' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'hub'+'bub' is 'HUBBUB'.
Can you help me to learn more?
(Other definitions for hubbub that I've seen before include "Confused sound of many voices" , "riot" , "Chaotic noise of crowd" , "General commotion" , "Sound of noisy voices" .)
