Quietly pass plaything that may be stuck in the hair (5)
I believe the answer is:
slide
I believe this clue is a triple definition!
'quietly pass' is the first definition.
(slide can mean to move quietly)
'plaything' is the second definition.
(slide is a kind of plaything)
'that may be stuck in the hair' is the third definition.
(as in a hairslide)
(Other definitions for slide that I've seen before include "Drop" , "Slip, slither, skid" , "that's put under the microscope" , "Trombone part" , "Playground item" .)
