Aria report backed to include Carmen? (5)
I believe the answer is:
opera
'carmen?' is the definition.
(Carmen is an example)
'aria report backed to include' is the wordplay.
'to include' indicates the answer is hidden within the clue.
'backed' says the letters should be written in reverse.
'arepo' is hidden in the letters of 'aria report'.
'arepo' backwards is 'OPERA'.
(Other definitions for opera that I've seen before include "Carmen, for instance" , "eg Otello" , "Eg, Il trovatore" , "Musical stage work" , "Met show?" .)
