Jazz great ____ Fitzgerald (4)
I believe the answer is:
ella
'jazz great fitzgerald' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ella that I've seen before include "- Wheeler Wilcox, US poet" , "Diminutive of Eleanor" , "Girl" , "Miss" , ".... Fitzgerald, late great jazz diva" .)
