A composer some opera-lover digs? (5)
I believe the answer is:
verdi
'a composer' is the definition.
(Italian composer Giuseppe Verdi)
'some opera-lover digs?' is the wordplay.
'some' indicates a hidden word (some parts of the word are used).
'VERDI' can be found hidden inside 'opera lover digs'.
(Other definitions for verdi that I've seen before include "Composer of the operas Macbeth, Falstaff" , "one put on at La Scala" , "Giuseppe _____, composer of "La Traviata"" , "Drive to meet great composer" , "Drive around to locate opera composer" .)
