Sex pest touring with a musical show (5,5)
I believe the answer is:
grand opera
'musical show' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'sex pest touring with a' is the wordplay.
'sex pest' becomes 'groper' (I can't explain this - if you can you should believe this answer much more).
'touring' means one lot of letters goes inside another (tour can mean to go around).
'with' becomes 'and'.
'groper' placed around 'and' is 'grandoper'.
'grandoper'+'a'='GRAND OPERA'
Can you help me to learn more?
(Other definitions for grand opera that I've seen before include "'Aida', for instance?" , "Musical entertainment" , "spectacle where nothing is spoken" , "Piano concerti could be regarded as such" , "major theatrical project" .)
