Toy handed to grateful girl, last of all (4)
I believe the answer is:
doll
'toy' is the definition.
(I know that doll is a type of toy)
'handed to grateful girl last of all' is the wordplay.
'last of all' suggests the final letters.
The final letters of 'handed to grateful girl' are 'DOLL'.
(Other definitions for doll that I've seen before include "Toy baby" , "Puppet" , "Play figure" , "Toy representing person" , "Child's plaything" .)
