"Coppélia" composer (7)
I believe the answer is:
delibes
'coppelia composer' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for delibes that I've seen before include "Sylvia's French composer, 1836-91" , "French composer, Leo (1836-91)" , "Leo -, Coppelia composer" , "Lakme composer" .)
