trying to determine if a noun is alienable or inalienable based on its meaning or its affiliation to a specific noun category (for instance, body parts) can be difficult. Variation by languages Although the relationships listed above are likely to be instances of inalienable possession, those that are ultimately classified as inalienable depend on conventions that are specific by language and culture. It is impossible to say that a particular relationship is an example of inalienable possession without specifying the languages for which that holds true. For example, neighbor may be an inalienable noun in one language but alienable in another. Additionally, in some languages, one entity can be both alienably possessed and inalienably possessed, and its type of possession is influenced by other properties of the sentence. Thus, whether a certain type of relationship is described as alienable or inalienable can be arbitrary. In that respect, alienability is similar to other types of noun classes such as grammatical gender. The examples below illustrate that the same phrase, the table's legs, is regarded as inalienable possession in Italian but alienable possession in French: (1b) is ungrammatical (as indicated by the asterisk). French cannot use the inalienable possession construction for a relationship that is alienable. {| !(1) !a. !Italian - inalienable possession relationship |- | | | |- ! ! b. !

He states that "rather than being a semantically defined category, inalienability is more likely to constitute a morphosyntactic or morphophonological entity, one that owes its existence to the fact that certain nouns happened to be left out when a new pattern for marking attributive possession arose." He considers that nouns that are "ignored" by a new marking pattern come to form a separate noun class. Morphosyntactic strategies for marking distinction The distinction between alienable and inalienable possession is often marked by various morphosyntactic properties such as morphological markers and word order. The morphosyntactic differences are often referred to as possession split or split possession, which refer to instances of a language making a grammatical distinction between different types of possession. In a language with possession split, grammatical constructions with alienable nouns will differ from constructions with inalienable nouns. There is
