A drawer of money (4)
I believe the answer is:
till
I believe this is a double definition.
'a drawer' is the first definition.
(I've seen this before)
'money' is the second definition.
(thesaurus)
'of' is the link.
(Other definitions for till that I've seen before include "Prepare land for cultivation by ploughing etc" , "Drawer holding money in shop." , "Container for money" , "Cultivate - cash register" , "Dig soil" .)
