nieregularnymi

Nieregularnymi is the instrumental plural form of the Polish adjective nieregularny, meaning irregular or non-regular. It is used to describe plural nouns in the instrumental case, for example when indicating irregular forms, irregular verbs, or other irregular items in a sentence.

Morphology and usage: nieregularnym is the base stem, and in the plural instrumental it becomes nieregularnymi. This form is the same across gender in the instrumental plural, so it can modify masculine personal, feminine, and neuter nouns in the plural. The adjective nieregularny follows standard Polish declension patterns, with nieregularnymi serving as the instrumental plural ending. It is commonly found in contexts discussing deviations from regular patterns in language, morphology, phonology, or other domains.

Examples of use: phrases such as z nieregularnymi formami (with irregular forms) or z nieregularnymi czasownikami (with irregular verbs) illustrate how nieregularnymi functions to specify irregularity in a plural instrumental context. The term is typical in linguistic descriptions, grammar guides, and educational materials addressing irregularity in Polish.

Etymology and related terms: nieregularnym derives from nie- (negative prefix) + regularny (regular), itself from Latin regularis through Romance languages. Related concepts include nieregularne czasowniki (irregular verbs), odmiana nieregularna (irregular inflection), and regularny (regular). In Polish language studies, nieregularnymi appears as a standard inflected form rather than as a stand-alone lexical item.
