Sprinkle into this wallet by the sound of it (8)
I believe the answer is:
disperse
'sprinkle' is the definition.
(I know that sprinkle can be written as disperse)
'this wallet by the sound of it' is the wordplay.
I cannot really understand how this works, but
'by' could be 'per' (I've seen this in another clue) and 'per' is found in the answer.
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is found in the answer.
The remaining letters 'diss' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'into' is the link.
Can you help me to learn more?
(Other definitions for disperse that I've seen before include "'Break up, spread out (8)'" , "Spread widely" , "Scatter, break up" , "Scatter in all directions" , "Break up, move away from each other" .)
