czystsza

Czystsza is the feminine singular comparative form of the Polish adjective czysty, meaning cleaner or purer. It is used to describe feminine nouns or feminine subjects and appears in constructions that compare cleanliness or purity relative to another state, for example in environmental or quality-related contexts.

Form and usage details: The base adjective czysty forms standard comparatives with czystszy (masculine), czystsza (feminine), and czystsze (neuter or plural). Therefore czystsza is the grammatically correct form before feminine nouns such as woda (water), energia (energy), okolica (surroundings), czy gleba (soil). Pronunciation is typically rendered as [ˈt͡ɕɨst͡ɕa]. In predicative use, it would appear as "jest czystsza" when referring to a feminine subject.

Common contexts: Czystsza is frequent in environmental, consumer, and policy language to indicate improvement. Examples include czystsza woda ( cleaner water ), czystsza energia ( cleaner energy ), or czystsza okolica ( cleaner surroundings ). It is also used in comparisons such as Woda w tej kranie jest czystsza niż rok temu, illustrating how the form functions in a sentence.

Relation to other forms: While czystsza refers to feminine nouns, czystszy and czystsze serve masculine and neuter or plural nouns respectively. In everyday usage, speakers choose the form to agree with the gender and number of the noun being described.

Note: Czystsza is a grammatical form rather than a separate concept or entity; it appears as part of the broader system of Polish adjectives describing relative quality or cleanliness. See also czysty, czystość.
