Woman, Verdi heroine who loses her head (3)
I believe the answer is:
ida
'woman' is the definition.
(woman's name)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for ida that I've seen before include "Greek mount - Gilbertian princess" , "lady" , "Girl's name; aid (anag.)" , "Classical mountain" , "Mountain in Crete" .)
