Aktivních

Aktivních is a form of the Czech adjective aktivní, meaning active. It is not a stand-alone noun; it appears as a declined ending used when the adjective modifies a plural noun in specific grammatical cases.

In Czech, adjectives decline for gender, number, and case. Aktivních is primarily the genitive plural form and the locative plural form. It is used when the modifying noun is in genitive plural (for example after numbers or words requiring the genitive) and in locative plural after prepositions such as o, v, or na.

Examples illustrate its use:

- Počet aktivních uživatelů se zvýšil. (The number of active users has increased.) Here aktivních is genitive plural, attached to uživatelů.

- O aktivních uživatelích se diskutovalo. (There was a discussion about active users.) Here aktivních is locative plural, following the preposition o.

The form can also appear with other plural nouns in same cases, such as aktivních lidí or aktivních zaměstnancích, depending on the noun being described and the required case.

Etymology and morphology: aktivní derives from Latin activus through Slavic linguistic development, with the Czech suffix -ní forming the adjective. The ending -ních is a characteristic plural inflection used for genitive and locative cases in many adjectives with a similar stem.

In usage, aktivních is common in formal and descriptive Czech, especially in contexts discussing groups of people or items that are characterized as active. It is one of several inflected forms of aktivní that writers select to match case and number.
