"Rent" role (4)
I believe the answer is:
mimi
'rent role' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for mimi that I've seen before include "I'm, I'm mad about the heroine in 'La Boheme'" , "Her tiny hand was frozen (Puccini)" , "Bohemian girl" , "Tragic Parisienne" , "unfortunate sewer" .)
