parních

Parní is a Czech adjective meaning "steam" or "steam-powered." It is used to describe machinery, processes, and phenomena related to steam, especially in the fields of engineering, industry, and history. Common terms include parní stroj (steam engine), parní lokomotiva (steam locomotive), parní motor (steam engine), and parní turbína (steam turbine). The form parní is inflected to agree with the noun it modifies.

The form parních is one of the inflected endings of parní. In standard Czech, parních typically represents the genitive plural form of the adjective, used when the modified noun is plural and in the genitive case. For example, in phrases such as výkon parních motorů (the performance of steam engines) or cena parních kotlů (the price of steam boilers), parních accompanies plural nouns in the genitive. The same adjective also appears in other cases and numbers with corresponding endings, but parní remains the base meaning “steam.”

Etymology and usage context clarify that parní derives from pára, meaning steam or vapor, and forms compounds to denote steam-related technology or era. The term is widely encountered in historical discussions of the steam age, engineering textbooks, and technical documentation. While parní by itself denotes the concept of steam, its celebrated role in industry is reflected in a multitude of compound terms that describe equipment and processes powered by steam energy.
