possessivepartitive

Possessive partitive is a theoretical grammatical construction that encodes both possession (ownership) and partitivity (partial quantity or portion) within a single expression or through closely linked morphological elements. The term appears in linguistic typology and morphology to describe how some languages express “a part of X that belongs to Y.”

Morphological realizations of the possessive partitive vary. In some languages, a single fused affix or clitic attached to the possessed noun carries both possession and partitive meaning. In others, possession is shown by a possessive determiner or suffix, while partitivity is indicated by a separate partitive marker or case. The exact form and order depend on the language’s phonology, morphology, and syntactic alignment.

Semantically, the construct signals that the referenced object is owned by someone and is not the whole or a definite unit. It is often used with mass or non-count nouns, with partial quantities, or with indefinite portions. The construction can influence determiner selection, case marking, and agreement, and it interacts with discourse factors such as definiteness and focus.

Cross-linguistically, possessive partitives are discussed in languages with rich possession morphology or with a distinct partitive system, notably in Finnic and related languages, though the specifics differ by language. Analyses range from treating the form as a single morpheme encoding dual functions to analyzing it as a possessive element plus a separate partitive marker.
