Baba of folklore (3)
I believe the answer is:
ali
'baba of folklore' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ali that I've seen before include "Muhammad - - , legendary boxer" , "Muhammad's son-in-law" , "Ringmaster" , "Egyptian name" , "Mohammad . . ., . . . Hewson" .)
