Inalienable possession

Property in the form of land was considered a relatively inalienable possession for Roman citizens. Human rights are considered an inalienable possession.
In linguistics, inalienable possession[1] (abbreviated inal) is a type of possession in which a noun is obligatorily possessed by its possessor. Nouns or nominal affixes in an inalienable possession relationship cannot exist independently or be "alienated" from their possessor.[2] Inalienable nouns include body parts (such as leg, which is necessarily "someone's leg", even if severed from the body), kinship terms (such as mother), and part-whole relations (such as top).[3]
