Christmas song for a girl (5)
I believe the answer is:
carol
I believe this is a double definition.
'christmas song' is the first definition.
(Christmas carol)
'girl' is the second definition.
(woman's name)
'for a' acts as a link.
(Other definitions for carol that I've seen before include "Canticle" , "Song celebrating the birth of Jesus" , "Christmas ditty" , "Religious song - girl's name" , "Joyful song - woman's name" .)
