bread

I'm a little stuck... Click here to teach me more about this clue!

'money' is the definition.
(bread is slang for money)

I don't understand how the rest of the clue works.

(Other definitions for bread that I've seen before include "It's made with 23" , "Dosh (slang)" , "Loaves" , "Baked food; money" , "Bloomers, say" .)
