Produced noted bananas (4)
I believe the answer is:
made
'produced' is the definition.
('make' can be a synonym of 'produce')
'noted bananas' is the wordplay.
I cannot really understand how this works, but
'bananas' could be 'mad' (slang for insane) and 'mad' is present in the answer.
A single letter 'e' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for made that I've seen before include "Performed" , "Produced" , "Forced" , "Built" , "One renovating (painting)" .)
