Part of Aida reportedly getting backing - that's what Verdi is famous for (5)
I believe the answer is:
opera
'part' is the definition.
(thesaurus)
'aida reportedly getting backing that's what verdi is famous for' is the wordplay.
'OPERA' is hidden back-to-front within the letters.
But, I am not sure how the hidden word is indicated.
'of' is the link.
Can you help me to learn more?
(Other definitions for opera that I've seen before include "musical presentation" , "Musical in which all the words are sung" , "La Scala production, perhaps" , ""Rigoletto", for example" , "eg Otello" .)
