"The Great” actress Fanning (4)
I believe the answer is:
elle
'the great actress fanning' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for elle that I've seen before include "French word for 'she'" , "World's best-selling fashion magazine" , "Fashion magazine - the French "She"" , "Ms MacPherson, supermodel" , "Is she in France" .)
