wiarygodnego

Wiarygodnego is the genitive singular masculine form of the Polish adjective wiarygodny, meaning credible or trustworthy. It describes information, sources, people, or data that can be relied upon.

Origin and meaning: The word derives from wiara (faith) and godny (worthy). Taken together, wiarygodny literally means worthy of trust. The genitive form wiarygodnego is used with certain nouns, for example in phrases like informacja pochodzi z wiarygodnego źródła (information from a credible source).

Grammatical use: In Polish, wiarygodnego appears in the genitive singular for masculine and neuter nouns, and in the accusative masculine animate when forms align with the genitive. For feminine nouns, the corresponding genitive singular form is wiarygodnej. This adjective also participates in typical decimal agreement: wiarygodny (nominative), wiarygodnego (genitive/accusative), wiarygodnej (genitive feminine), and so on.

Usage and nuance: The term is common in journalism, academia, and formal writing to qualifier statements or sources as dependable. It is closely related to synonyms such as rzetelny and autentyczny, but emphasizes trustworthiness rather than just factual accuracy. Its antonym is niewiarygodny, meaning unbelievable or dubious, used to flag information that lacks credibility.
