Solo work about rascal in classical rural setting (7)
I believe the answer is:
arcadia
'classical rural setting' is the definition.
'arcadia' can be an answer for 'setting' (I have seen 'pastoral setting' mean 'arcadia' so perhaps 'setting' could also mean 'arcadia'). I'm not sure about the 'classical rural' bit.
'solo work about rascal' is the wordplay.
'solo work' becomes 'aria' (I can't justify this - if you can you should believe this answer much more).
'about' is an insertion indicator.
'rascal' becomes 'cad' (both can mean a dishonourable person).
'aria' placed around 'cad' is 'ARCADIA'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for arcadia that I've seen before include "ideal place in the country" , "rural area" , "Idyllic country of song-loving shepards" , "modern play" , "Tom Stoppard play" .)
