Brontë sister (4)
I believe the answer is:
anne
'bronte sister' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for anne that I've seen before include "Last Stuart monarch, d. 1714" , "One of the Bronte sisters" , "Henry's second" , "Queen 1702-1714" , "Prince Charles's sister" .)
