Soprano on debut is charming (9)
I believe the answer is:
entrances
'is charming' is the definition.
I can't judge whether this definition defines the answer.
'soprano on debut' is the wordplay.
'soprano' becomes 's' (musical abbreviation).
'on' means one lot of letters go next to another.
'debut' becomes 'entrance' (I've seen this in another clue).
's' after 'entrance' is 'ENTRANCES'.
Can you help me to learn more?
(Other definitions for entrances that I've seen before include "Fills with delight" , "Delights" , "Charms" , "make appearances on stage" , "Transports" .)
