Chemicznej

Chemicznej is a form of the Polish adjective chemiczny, meaning chemical. It is used with feminine nouns and appears in several grammatical cases in the singular. Specifically, chemicznej is the feminine singular genitive, dative, and locative form of the adjective, while the nominative and accusative forms differ (chemiczna and chemiczną, respectively).

In practice, chemicznej occurs when a feminine noun is described in cases other than the nominative or accusative. For example, with the feminine noun substancja (substance): substancja chemiczna (nominative), substancji chemicznej (genitive), do substancji chemicznej (dative), substancję chemiczną (accusative), substancją chemiczną (instrumental), o substancji chemicznej (locative). The form chemicznej thus marks a relationship such as possession, indirect object, or aboutness for a chemical substance.

The adjective chemiczny and its forms are widely used in scientific and technical Polish to describe chemical properties, processes, or materials. Common collocations include chemiczny proces, chemiczna substancja, chemiczna reakcja, and related phrases where gender and case agreement ensure grammatical correctness within Polish sentence structure.

Understanding chemicznej requires recognizing its role within the feminine noun phrase and its placement within the broader system of Polish declension for adjectives. This enables precise description of chemical entities in written and spoken Polish.
