nutné

Nutné is the neuter singular form of the Czech adjective nutný, meaning necessary or required. It is used to express that something must be done or is essential under given circumstances. Nutné can function predicatively, as in “Je nutné,” meaning “It is necessary,” often followed by an infinitive, and it can also appear attributively before neuter nouns such as “nutné opatření” (necessary measure) or “nutné minimum” (the necessary minimum). In plural or different genders the other forms apply: masculine “nutný,” feminine “nutná.”

In addition to nutné as a neuter attribute, Czech also uses the impersonal particle nutno in fixed expressions, for example “Nutno dodat” (It must be added) or “Nutno říci” (It must be said). The word is related to related terms such as nutnost (necessity) and nutný as an adjective describing obligation or indispensability. In technical or formal language it may occur in phrases like “nutná podmínka” (a necessary condition) in logic or mathematics, where it designates a condition that must hold for a given statement or event.

Etymology traces nutný to a Proto-Slavic root meaning “need,” linked with the noun nutnost (necessity). Related forms include nutno and nutně, the latter serving as an adverb meaning “urgently” or “pressingly” in some contexts, though with nuance distinct from the core meaning of “necessary.”

Overall, nutné is a common, neutral term used to indicate necessity in everyday language, formal statements, and technical contexts.
