Lust for money (3)
I believe the answer is:
yen
I believe this is a double definition.
'lust' is the first definition.
(thesaurus)
'money' is the second definition.
(Japanese currency)
'for' acts as a link.
(Other definitions for yen that I've seen before include "Intense longing" , "Long for a coin" , "Long for Japanese money?" , "Intense desire for a Japanese coin" , "Longing, hankering after" .)
