I'm top name in performance: Cinderella? (9)
I believe the answer is:
pantomime
'performance cinderella?' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'i'm top name' is the wordplay.
'i'm top name' anagrams to 'PANTOMIME'.
But, I'm unsure how this is indicated.
'in' is the link.
Can you help me to learn more?
(Other definitions for pantomime that I've seen before include "Christmas theatre, usually with Dame" , "Mime on tap in children's show" , "Festive stage show" , "Play performed at Christmas" , "'Cinderella', for example" .)
