Mobilními

Mobilními is the instrumental plural form of the Czech adjective mobilní, meaning "mobile" or "portable." In Czech, adjectives agree with the nouns they modify in gender, number, and case, and mobilní takes different endings accordingly. The instrumental plural form mobilními is used with masculine inanimate or mixed-gender plural nouns when the action or relation is expressed with a preposition or verb that requires the instrumental case.

Morphology and usage example: The base form mobilní is used in the nominative plural as mobilní, but when describing objects in instrumental plural, the ending changes to mobilními. For example: s mobilními telefony (with mobile phones), v rámci mobilními zařízeními (within with mobile devices). The form mobilními appears after prepositions such as s (with), bez (without), mezi (between) and in predicates that require the instrumental case in plural.

Context and notes: Mobilní is widely used in technology-related vocabulary to describe portable devices and services, such as mobilní telefony, mobilní sítě, nebo mobilní aplikace. Beyond technology, the instrumental plural form mobilními can appear in various contexts where plural nouns denoting portable or movable things are involved. The form is specific to Czech, while Slovak uses analogous instrumental plural forms with slight orthographic differences (for example mobilnými). Understanding mobilními helps in correctly constructing phrases that indicate means, accompaniment, or instrumentality in plural, such as “s mobilními zařízeními” or “pomocí mobilními funkcemi,” depending on standard grammar rules.
