Event for Cinderella (4)
I believe the answer is:
ball
'event for cinderella' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ball that I've seen before include "that one might throw?" , "Old song: 'After the .... was over'" , "Spherical object" , "Sphere; function" , "Bouncer, say" .)
