Bread? Yes and no (5)
I believe the answer is:
dough
'bread?' is the definition.
(both can informally mean money)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for dough that I've seen before include "Money (sl.)" , "Flour and water mix; money" , "Floury mixture" , "Bready mix" , "Paste; money" .)
