czystszych

Czystszych is a form of the Polish adjective czysty (clean, pure) in the comparative degree. It expresses a higher degree of cleanliness or purity and is used when describing plural nouns in contexts that require the genitive or accusative case, typically after prepositions that govern those cases.

Grammatically, czystszych is the form used with plural nouns in genitive or accusative cases when the comparative czystszy is applied. The stem czyst- combines with the comparative suffix -szy, and the ending -ych marks the genitive/accusative plural for many adjectives. This form contrasts with czystsze (neuter singular) and czystszy (masculine singular), which appear in other grammatical contexts.

Usage notes and examples:

- After prepositions requiring genitive, such as wśród or bez, czystszych commonly appears with a plural noun: wśród czystszych źródeł (among purer sources).

- In comparative constructions with od (than), czystszych is used with plural nouns in genitive: czystszych od poprzednich próbek (purer than the previous samples).

- In standard predicative position with a plural subject, czystsze is used instead of czystszych: Próbki były czystsze od poprzednich (the samples were purer than the previous ones).

Related forms and etymology:

- The base form czysty means clean or pure; czystszy is the comparative form; czystszych is the plural genitive/accusative form of the comparative.

- Related words include czystość (purity/cleanliness) and czystsze (neuter plural or positive comparative in other contexts).
