Part of air from soprano, grandly making comeback (5)
I believe the answer is:
argon
'part of air' is the definition.
The answer and definition can be both substances as well as being singular nouns.
Maybe there's a link between them I don't understand?
'from soprano grandly making comeback' is the wordplay.
'from' says the answer is hidden in the clue.
'making comeback' says the letters should be written in reverse.
'nogra' is hidden in the letters of 'soprano grandly'.
'nogra' in reverse letter order is 'ARGON'.
Can you help me to learn more?
(Other definitions for argon that I've seen before include "Gas, 1% of atmosphere" , "Inert gas, symbol Ar" , "Gaseous element" , "Noble gas used in light bulbs" , "Inert eighteen ac gas" .)
