Return of postwar child asking ice runner out (9)
I believe the answer is:
boomerang
'return' is the definition.
(boomeranging is a kind of returning)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for boomerang that I've seen before include "Australian throwing stick" , "Aboriginal throwing stick" , "Aboriginal projectile" , ""It keeps coming back"" , "Primitive weapon" .)
