Woman who expects to succeed? (7)
I believe the answer is:
heiress
'woman who expects to succeed?' is the definition.
(someone who will succeed to property)
This is all the clue.
(Other definitions for heiress that I've seen before include "Inheritrix" , "One coming into wealth" , "Woman who will inherit great wealth" , "Portia, say" , "Female will beneficiary" .)
