Britten speciality accepted by Europe? Radical (5)
I believe the answer is:
opera
'britten speciality' is the definition.
The definition suggests a singular noun which matches the answer.
'accepted by europe? radical' is the wordplay.
'OPERA' is hidden within the letters.
However, I'm uncertain how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for opera that I've seen before include "Throw a rope for this show" , "Musical dramatic work" , "E.g. Macbeth, Falstaff" , ""The Magic Flute", for example" , "Lulu, say" .)
