Italian operatic composer (5)
I believe the answer is:
verdi
'italian operatic composer' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for verdi that I've seen before include "Italian opera composer" , "Drive to meet great composer" , "Diver became a strange composer" , "Emblem of the Knights Hospitallers" , "Giuseppe _____, composer of "La Traviata"" .)
