Florida resort without a role for a soprano (4)
I believe the answer is:
mimi
'role for a soprano' is the definition.
(mimi doulton)
'florida resort without a' is the wordplay.
'florida resort' becomes 'miami' (I've seen this before).
'without' indicates named letters should be taken away.
'miami' with 'a' taken out is 'MIMI'.
(Other definitions for mimi that I've seen before include "Starving character of "La Boheme"" , "showgirl" , "unfortunate sewer" , "Puccini heroine" , "Tragic Parisienne" .)
