Bocznej

Bocznej is a grammatical form in the Polish language. It is not a standalone lexical item, but the feminine form used in various cases of the adjective boczny (or boczna) meaning “lateral” or “side.” Specifically, bocznej can function as the feminine genitive singular, feminine dative singular, or feminine locative singular of the adjective when it modifies a feminine noun.

The form derives from the root bok, meaning “side” or “edge,” combined with a typical Polish adjective inflection. Its appearance reflects standard agreement rules in Polish, where adjectives agree in gender, number, and case with the nouns they modify. In practice, bocznej appears in several common constructions describing the side or lateral position of objects or places.

Bocznej is widely used in technical and everyday language. In anatomy or architecture one might encounter phrases such as okno bocznej ściany (the window of the side wall) or krawędź bocznej drogi (the edge of a side road). In geography or urban contexts it can appear in expressions like na bocznej ulicy (on the side street) or bocznej części miasta (the side part of the city). Because the form is case-specific, its exact spelling may vary to bocznej, depending on grammatical role and the accompanying noun.
