Jane Austen classic
I believe the answer is:
'jane austen classic' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for emma that I've seen before include "Jane Austen work - Ms Bunton, former Baby Spice" , "Flaubert's heroine" , "Best Actress Oscar winner 1992, for 'Howard's End'" , "Jane Austen heroine" , "It's a girl - ask me ma" .)
