narzdziowy

Narzędziowy is a term found in some linguistic and grammatical descriptions to denote the instrumental function in Polish. In standard Polish grammar the instrumental case is called narzędnik, while narzędziowy appears as an adjectival label used in descriptive or historical contexts to refer to the instrumental form or its uses. The term can therefore appear in teaching materials, grammars, and linguistic discussions as a way to describe the instrumentality of a word or phrase.

Use and meaning:

The instrumental case marks the means or instrument by which an action is performed, and it can express the manner in which something is done. In everyday Polish, it is used after verbs to indicate the instrument of an action: for example, piszę długopisem (I write with a pen). It also appears in phrases that express accompaniment or certain grammatical constructions where the instrument or means is foregrounded.

Morphology and examples:

The instrumental singular typically has endings that vary by gender and declension class. Common examples include długopisem (from długopis), narzędziem (from narzędzie), kobieta → kobietą, and stół → stołem. The instrumental plural appears as długopisami, narzędziami, etc. The exact form depends on the noun’s paradigm and phonological pattern.

Relation to narzędnik:

While the standard term for the case is narzędnik, narzędziowy is encountered as an alternative or descriptive label in some sources. It is not the official name of the case but a way to reference its instrumental function in linguistic discussions. See also narzędnik, mianownik, and other Polish case names.
