"La Boheme" role (4)
I believe the answer is:
mimi
'la boheme role' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for mimi that I've seen before include "Her tiny hand was frozen (Puccini)" , "unfortunate sewer" , "Tragic heroine" , "La Boheme character (whose tiny hand is frozen)" , "Puccini's seamstress" .)
