Sweetie money? (5)
I believe the answer is:
lolly
This clue could be a double definition.
'sweetie' is the first definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'money?' is the second definition.

Can you help me to learn more?
(Other definitions for lolly that I've seen before include "Money (sl.)" , "A sweet; money (slang)" , "Cash (slang)" , "Flavoured iced water" , "Sweet, money (colloq.)" .)
