niejednorodnej

Niejednorodnej is the feminine singular genitive (and also dative or locative in some contexts) form of the Polish adjective niejednorodny, meaning not homogeneous or not uniform. The prefix nie- marks negation of the base meaning jednorodny (uniform, homogeneous). The form niejednorodnej is used when the noun it describes is feminine and in the genitive, dative, or locative case, for example in phrases such as niejednorodnej materii or niejednorodnej dystrybucji. The corresponding nominative feminine form is niejednorodna, and neuter singular is niejednorodne.

In linguistic terms, niejednorodny and its inflected forms describe things characterized by nonuniformity or heterogeneity. This term is common in scientific and technical language as well as in everyday speech when indicating irregularity, variety, or spatial variation within a substance, system, or distribution.

Usage across fields is broad. In physics and materials science one may speak of właściwości niejednorodnej materii (properties of inhomogeneous matter) or gęstość niejednorodnej dystrybucji (density of an inhomogeneous distribution). In geography, biology, or network theory one might refer to struktura niejednorodnej sieci (structure of a nonuniform network) or rozkład niejednorodnej populacji (distribution of an inhomogeneous population). The term appears in both descriptive and analytical contexts, where emphasis is on nonuniformity or spatial variation rather than uniformity.
