uhlíkovými

Uhlíkovými is the instrumental plural form of the Czech adjective uhlíkový, meaning carbon-containing or carbon-related. It is used to modify nouns in the instrumental case, typically in scientific or technical contexts. Common collocations include s uhlíkovými sloučeninami (with carbon compounds), uhlíkovými částicemi (with carbon particles), or uhlíkovými vlákny (with carbon fibers).

Etymology and grammar: The word is derived from uhlík (carbon) with the suffix -ový, forming the adjective uhlíkový. In the instrumental plural, the ending becomes -ými, yielding uhlíkovými. This form agrees with masculine inanimate, feminine, and neuter nouns in the instrumental plural.

Usage: Uhlíkovými is frequent in chemistry, materials science, environmental science, and industry when describing carbon-related properties, substances, or components. It should be distinguished from related terms such as uhlíková (feminine singular or neuter plural) or uhlík, which denote the noun carbon itself. The phrase uhlíkovými sloučeninami, for example, conveys activity or analysis involving carbon compounds.

Notes: As with other adjectives, the exact form adapts to the gender, number, and case of the noun it modifies. The instrumental plural uhlíkovými is most commonly encountered after prepositions that govern the instrumental case (for example, s).
