Remain and hunt for what's left (7)
I believe the answer is:
bequest
'what's left' is the definition.
I can't judge whether this definition defines the answer.
'remain and hunt' is the wordplay.
'remain' becomes 'be' (I've seen this in other clues).
'and' is a charade indicator (letters next to each other).
'hunt' becomes 'quest' (quest is a kind of hunt).
'be'+'quest'='BEQUEST'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for bequest that I've seen before include "Gift by will of personal property" , "Something gifted in a will" , "Endowment, legacy" , "One left in will" , "Something left in a will (7)" .)
