Girl's name; boomerang (5)
I believe the answer is:
kylie
I believe this is a double definition.
'girl's name' is the first definition.
'boomerang' is the second definition.
(I know that kylie is a type of boomerang)
(Other definitions for kylie that I've seen before include "Type of boomerang" , "Dannii M's older sister" , "-- Minogue, Australian singer" , "returning missile" , "Aussie singer" .)
