Little money for girl (5)
I believe the answer is:
penny
This clue is a double definition.
'little money' is the first definition.
(small amount of money)
'girl' is the second definition.
(woman's name)
'for' acts as a link.
(Other definitions for penny that I've seen before include "Coin - girl's name" , "Smallest UK coin" , "1p" , "p; small coin" , "one might drop" .)
