rodzaju

Rodzaju is the genitive singular form of the Polish noun rodzaj, which means kind, type, category, or grammatical gender. The term is used across several domains of language, and it also appears in scientific terminology.

In grammar, rodzaj denotes a grammatical category that classifies nouns, pronouns, and adjectives into masculine, feminine, and neuter in Polish. The form rodzaju occurs in phrases describing this category, for example: rodzaju męskiego (masculine gender) and rodzaju żeńskiego (feminine gender). The expression różnego rodzaju (of various kinds) is a common collocation in Polish.

In biology, rodzaj corresponds to the genus in taxonomic classification. The genitive singular rodzaju is found in phrases describing taxa, such as gatunek z rodzaju Homo (a species from the genus Homo). In this usage, rodzaj serves to indicate the rank of genus and is combined with the name of the genus.

Etymology and morphology: rodzaj originates from older Slavic roots, and its inflected form rodzaju follows standard Polish declension patterns for masculine nouns ending in -aj in singular genitive. The form is frequently encountered in written and spoken Polish, particularly in formal or academic contexts.
