"Shy” singer DiFranco (3)
I believe the answer is:
ani
'shy singer difranco' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ani that I've seen before include "Bird of the cuckoo family" , "Indigo dye." , "Black bird" , "One winged" , "Tropical bird" .)
