mladistvých

Mladistvých is a genitive plural form of the Czech adjective mladistvý, meaning youthful or juvenile. It functions as part of the adjective phrase that describes a plural noun in the genitive case, indicating “of the young” or “belonging to the youth.”

In ordinary usage, mladistvých appears before a noun in genitive plural, for example mladistvých dívek (of the young girls), mladistvých mužů (of the young men), or mladistvých osob (of the young people). The form is gender-neutral in its grammatical function, applying across masculine, feminine, and neuter nouns in the genitive plural. This is a common pattern for Czech adjectives ending in -ý in the masculine singular.

Semantically, mladistvý describes youthfulness in appearance, behavior or characteristics, and mladistvých is simply the grammatical vehicle for referencing such qualities when talking about groups in the genitive case. The adjective can be contrasted with the related noun mladistvost, which denotes the state or quality of being youthful.

Etymology and related forms: mladistvý is formed from the adjective mladý (young) with the derivational element -istv-, yielding the meaning “youthful.” The noun mladistvost (youthfulness) is related in meaning but grammatically distinct.
