Legal entitlement this person in senate renegotiated (8)
I believe the answer is:
easement
'legal entitlement' is the definition.
The definition suggests a singular noun which matches the answer.
'this person in senate renegotiated' is the wordplay.
'this person' becomes 'me' (the person writing).
'in' indicates putting letters inside.
'renegotiated' is an anagram indicator.
'senate' with letters rearranged gives 'easent'.
'me' going into 'easent' is 'EASEMENT'.
Can you help me to learn more?
(Other definitions for easement that I've seen before include "right of passage" , "landowner's right" , "Right to cross another's property; peace" , "The legal right to cross or use another's land" , "giving right of access to adjacent area?" .)
