Jane Austen heroine (4)
I believe the answer is:
emma
'jane austen heroine' 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 "book" , "Flaubert's heroine" , "Ack -, a term for a.m." , "young woman in novel" , "Best Actress Oscar winner 1992, for 'Howard's End'" .)
