Desire for money (3)
I believe the answer is:
yen
I believe this clue is a double definition.
'desire' is the first definition.
(yen is a kind of desire)
'money' is the second definition.
(Japanese currency)
'for' is the link.
(Other definitions for yen that I've seen before include "Longing for a currency unit" , "foreign currency" , "Intense longing" , "Unit of money in Japan" , "Longing (colloq.)" .)
