Money produced after investment by America (5)
I believe the answer is:
bread
'money' is the definition.
(slang term for money)
'produced after investment by america' is the wordplay.
I cannot quite see how this works, but
'america' could be 'a' (common abbreviation - e.g. in organisation names) and 'a' is located in the answer.
'produced' could be 'bred' (breeding is a kind of producing) and 'bred' is present in the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for bread that I've seen before include "Gracefully thin" , "Baked food; money" , "Food; money (informal)" , "rhino" , "Eg, loaf or rolls" .)
