vodního

Vodního is the genitive singular masculine and neuter form of the Czech adjective vodní, which means “water-related” or “hydro-.” The base adjective vodní describes something pertaining to water and is used in a wide range of contexts, from science and geography to everyday language.

In Czech, vodní is a productive modifier in attributive position, meaning it commonly precedes the noun it describes (for example, vodní elektrárna, hydroelectric power plant). The form vodního appears when the noun is masculine or neuter and in the genitive case, as in vodního charakteru (of a water-related character), vodního zdroje (of the water source), or vodního průmyslu (of the hydro industry). The feminine forms and other cases follow standard Czech adjective declension patterns.

Usage and scope: vodní is used to indicate relation to water in technical terms (hydrology, environmental science, engineering) as well as in everyday expressions. It is often found in compound terms describing features of bodies of water, water-related infrastructure, and aquatic phenomena, such as vodní hladina (water surface), vodní tok (watercourse), and vodní plocha (water area).

Etymology: vodní is derived from voda, meaning water, with the adjectival suffix -ní to form a modifier indicating relation to water. The related form vodního is simply one inflected variant used with masculine or neuter nouns in genitive.
