Support a Verdi opera (4)

I believe the answer is:

aida

'verdi opera' is the definition.
(I've seen this before)

'support a' is the wordplay.
'support' becomes 'aid' ('aid' can be a synonym of 'support').
'aid'+'a'='AIDA'

(Other definitions for aida that I've seen before include "Verdi's Egyptian opera" , "title role" , "work of grand proportions" , "Operatic lady" , "eponymous heroine" .)

I've seen this clue in The Telegraph.
