Money for loaf (5)
I believe the answer is:
bread
This clue is a double definition.
'money' is the first definition.
(bread is a kind of money)
'loaf' is the second definition.
(I've seen this before)
'for' acts as a link.
(Other definitions for bread that I've seen before include "Loaves" , "Baker's product" , "Dosh - a bloomer, perhaps?" , "Food; money (informal)" , "It may be made from meal" .)
