biologicznej

Biologicznej is a form of the Polish adjective biologiczny, meaning biological. It is a feminine singular inflection used to describe feminine nouns and appears in different cases depending on the sentence. It is not a standalone lexical item with a separate meaning; rather, it is a grammatical form that agrees with the noun it modifies.

In Polish, adjectives change endings to reflect gender, number, and case. For feminine singular, the basic nominative form is biologiczna (for example, substancja biologiczna, a biological substance). The form biologicznej occurs in the genitive, dative, and locative cases (for feminine singular nouns), as well as in the accusative and instrumental when the sentence requires those cases. For instance:

- Nominative: substancja biologiczna

- Genitive: substancji biologicznej

- Dative: substancji biologicznej

- Accusative: substancję biologiczną

- Instrumental: substancją biologiczną

- Locative: o substancji biologicznej or w substancji biologicznej

Etymology and related terms: biologicznej is derived from biologiczny, itself from biologia and the typical Polish adjective suffix -iczny. Related forms include biologiczna (nominative feminine singular), biologiczne (neuter or plural), and biologiczny (masculine singular). The term is widely used in scientific, educational, and everyday language to describe attributes, processes, or objects connected with biology, such as nauka biologiczna (biological science), hodowla biologiczna (biological cultivation), or komponenty biologiczne (biological components).

Usage notes: Because it is a grammatical form, biologicznej cannot stand alone as a concept; it must modify a feminine noun and reflect the appropriate case. It contrasts with forms like biologiczny (masculine), biologiczna (nominative feminine), or biologiczne (neuter/plural).
