Some supper for meritorious singer, perhaps (9)
I believe the answer is:
performer
'singer perhaps' is the definition.
(singer is a kind of performer)
'some supper for meritorious' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'PERFORMER' can be found hidden inside 'supper for meritorious'.
(Other definitions for performer that I've seen before include "Entertainer" , "star?" , "Artiste" , "Fred Astaire, say" , "Such as a musician or actor" .)
