Illustrating the wide range of possible classifying principles for nouns, the [[Awa language (Papua New Guinea)|Awa language]] of [[Papua New Guinea]]<ref>{{cite web |url=https://glossary.sil.org/term/inalienable-noun |title=Inalienable Noun |author=<!--Not stated--> |date=3 December 2015 |publisher=[[SIL International]] |access-date= 6 February 2020}}</ref> regiments nouns according to how ''ownership'' is assigned: as alienable possession or [[Inalienable possession|inalienable]] possession. An alienably possessed item (a tree, for example) can exist even without a possessor. But inalienably possessed items are necessarily associated with their possessor and are referred to differently, for example with nouns that function as kin terms (meaning "father", etc.), body-part nouns (meaning "shadow", "hair", etc.), or part–whole nouns (meaning "top", "bottom", etc.).
