Not left any entitlement (5)
I believe the answer is:
right
This might be a double definition.
'not left' is the first definition.
('right' is the opposite to 'left')
'any entitlement' is the second definition.
'right' can be an answer for 'entitlement' (right can mean an entitlement to something). I'm not certain of the 'any' bit.
Can you help me to learn more?
(Other definitions for right that I've seen before include "Fair or just" , "Genuine" , "Girth (anag)" , "One has a claim to be correct" , "Correct; entitlement" .)
