kolistym

Kolistym is the instrumental singular masculine form of the Polish adjective kolisty, meaning circular or ring-shaped. In Polish, adjectives decline to agree with the gender, number, and case of the nouns they modify; kolistym is used when the described masculine noun is in the instrumental case.

As a morphological form, kolistym does not denote a standalone concept or entity. Instead, it serves a grammatical function, typically appearing in phrases that describe appearance or shape in an instrumental context. A common example is the expression w kolistym kształcie, meaning “in a circular shape,” where kolistym modifies the noun kształcie (shape) in the appropriate case form.

Etymology and usage: kolisty derives from koło, the Polish word for circle, with the suffix -isty forming an adjective meaning “circular.” The form kolistym is part of the standard Polish adjective declension pattern and is used when the modified masculine noun is in the instrumental singular. In broader texts, kolisty and its inflected forms describe objects or figures that are round or ring-shaped, including geometric, design, or biological contexts.

Notes: Kolistym is a routine grammatical form rather than a separate lexical item. For other genders and cases, the adjective has corresponding inflected forms (e.g., kolisty, kolista, koliste in nominative) depending on the noun it describes.
