To get money, you need audacity (5)
I believe the answer is:
brass
'audacity' is the definition.
(I've seen this in another clue)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for brass that I've seen before include "memorial in church" , "Ready" , "Alloy of copper and zinc" , "Rhino" , "It's there, if muck's there" .)
