A tune reversed in Nessun Dorma? (4)
I believe the answer is:
aria
'nessun dorma?' is the definition.
I can't tell whether this definition defines the answer.
'a tune reversed' is the wordplay.
'tune' becomes 'air' (air can mean a piece of music).
'reversed' says the letters should be written backwards.
'air' reversed gives 'ria'.
'a'+'ria'='ARIA'
'in' is the link.
Can you help me to learn more?
(Other definitions for aria that I've seen before include "Musical performance" , "Operatic song" , "Vocal solo in a cantata etc" , "Summertime perhaps" , "Operatic air" .)
