A wad of notes - bread! (4)
I believe the answer is:
roll
This could be a double definition.
'a wad' is the first definition.
(I've seen this in another clue)
'notes bread' is the second definition.
'roll' can be an answer for 'bread' (roll is a kind of bread). I'm not sure about the 'notes' bit.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for roll that I've seen before include "movement of ship" , "Small rounded bread" , "start a revolution" , "Revolve - piece of bread" , "Sound of a drum or a list of names" .)
