French singer Edith (4)
I believe the answer is:
piaf
'french singer edith' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for piaf that I've seen before include "French singer, the Little Sparrow, d. 1963" , "French singer who regretted nothing" , "Edith, the "Little Sparrow"" , "Edith -, Fr. cabaret singer (Non, je ne regrette rien)" , "Edith -, twentieth century French cabaret singer" .)
