mocný

Mocný is a Czech adjective meaning powerful, mighty, or strong. It is used to describe people, institutions, or phenomena that possess substantial power, authority, or influence. The sense can be literal, as in military strength, or figurative, as in a “mocný vliv” or a “mocná osobnost.” In everyday language the term is neutral and widely used in political, historical, and literary contexts.

In grammar, mocný agrees with gender and number: masculine singular mocný; feminine mocná; neuter mocné; plural mocní (masculine), mocné (feminine or neuter). The comparative form is mocnější and the superlative nejmocnější. The word appears in common phrases such as “mocný vliv,” “mocná říše,” or “mocný stát.”

Etymology traces mocný to the noun moc meaning power or authority. The root is shared across Slavic languages; related forms appear in Polish moc, Russian moc’ and other languages. The relationship between the adjective mocný and the noun moc is central to its use in describing levels of influence and control.

Mocný also exists as a surname in the Czech Republic and Slovakia. As a surname, it may not directly reflect the adjective’s meaning in every case, but it is attested as a family name in Czech- and Slovak-speaking regions.
