nieistniejcych

Nieistniejących is the genitive plural form of the Polish adjective and present participle nieistniejący, meaning "not existing" or "nonexistent." The base nieistniejący is built from the negation prefix nie- attached to the verb istnieć (to exist) with the present participle suffix -ący, yielding a word that describes something that does not exist. As a declined adjective, nieistniejący has a distinct genitive plural form: nieistniejących.

In use, nieistniejących modifies a masculine personal or mixed noun in the genitive plural. Examples include nieistniejących miejsc (of non-existent places), nieistniejących dowodów (of non-existent evidence), or nieistniejących faktów (of non-existent facts). The form cannot stand alone as a noun; it functions as an attributive or predicative adjective, agreeing with the noun it accompanies.

Context and nuance matter when choosing phrasing. nieistniejących conveys a strong sense of absence or nonexistence, often appearing in formal, analytical, or legal-language contexts, as well as philosophical discourse when distinguishing what does not exist from what does. In everyday speech, more direct constructions such as "nie ma" (there is no) are common for concrete referents, while nieistniejących appears where precision about nonexistence is desired.

Etymology: the word combines the negation prefix nie- with istnieć (to exist). The resulting adjective/participle can function in various grammatical roles and inflects like other Polish adjectives.

Notes: The form nieistniejących is specific to genitive plural; other forms of nieistniejący follow standard agreement patterns for adjectives across gender and number.
