Right to cross oriental people in the Orient (8)
I believe the answer is:
easement
'right' is the definition.
(thesaurus)
'to cross oriental people in the orient' is the wordplay.
'to cross' is an insertion indicator.
'oriental' becomes 'e'.
'people' becomes 'men' (men can refer to humanity as a whole).
'in' is an insertion indicator.
'the orient' becomes 'east' (synonyms).
'men' put into 'east' is 'easment'.
'e' inserted into 'easment' is 'EASEMENT'.
(Other definitions for easement that I've seen before include "Right to cross another's property; peace" , "right of passage" , "giving right of access to adjacent area?" , "landowner's right" , "The legal right to cross or use another's land" .)
