Soprano Adelina (5)
I believe the answer is:
patti
'soprano adelina' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for patti that I've seen before include "Adelina --, opera singer (1843-1919)" , "Soprano" , "Italian singer" , "Adelina -, nineteenth to twentieth century sopr." .)
