Czynnej

Czynnej is the feminine singular form of the Polish adjective czynny, meaning active, operating, or functioning. It functions as an inflected form used to modify feminine nouns and appears in the genitive, dative, or locative cases.

In practice, czynnej occurs whenever a feminine noun is in one of these cases and the adjective describes that noun. The most common contexts are noun phrases in genitive and locative cases, such as those found in service or operational terminology. For example, in the genitive phrase jakość czynnej obsługi means “the quality of active service,” and in the locative phrase o czynnej obsłudze means “about active service.” These examples illustrate how the form agrees with a feminine noun (obsługa) in the relevant case.

Grammatically, czynnej is one link in a broader system of Polish adjective agreement. The base adjective czynny has related forms such as czynna (nominative feminine) and czynne (nominative neuter or plural), with other cases produced through standard inflection.

Etymology and meaning: czynny derives from Polish czyn, root related to action or activity, and is connected to nouns such as czynność (activity or action). The form czynnej specifically encodes feminine gender and the genitive, dative, or locative case, depending on the syntactic role of the modified noun.
