Scares female away, which one's entitled to (6)
I believe the answer is:
rights
'which one's entitled to' is the definition.
(as in a person's legal rights)
'scares female away' is the wordplay.
'scares' becomes 'frights' ('fright' can be a synonym of 'scare').
'female' becomes 'f' (abbreviation).
'away' suggests deleting specific letters.
'frights' with 'f' taken away is 'RIGHTS'.
(Other definitions for rights that I've seen before include "They should balance responsibilities" , "Legal entitlements" , "A person is entitled to them" , "Legal entitlemants" , "power to publish works" .)
