Daughter of Lear (7)
I believe the answer is:
goneril
'daughter of lear' is the definition.
(one of King Lear's daughters)
This is the entire clue.
(Other definitions for goneril that I've seen before include "Female character in King Lear" , "Shakespearean role" , "A daughter of King Lear" , "Cruel daughter" , "her sister chose Cornwall" .)
