Wiarygodnych

Wiarygodnych is the genitive plural form of the Polish adjective wiarygodny, meaning credible or trustworthy. It is used to describe plural nouns in cases that require the genitive or in the locative after certain prepositions. The form is common in contexts such as discussing sources, information, or data that are deemed reliable.

Etymology and grammar: wiarygodny derives from wiara (faith) and godny (worthy). In Polish, adjectives decline for gender, number, and case. The genitive plural and the locative plural share the form wiarygodnych, which is used with masculine, feminine, and neuter nouns when the noun is in genitive plural or locative plural, for example after prepositions z, na, w, or bez, depending on the phrase.

Usage notes: wiarygodnych typically modifies nouns indicating credibility, such as źródła (sources), informacje (information), lub dane (data). Common collocations include wiarygodne źródła informacji (credible sources of information) and dane z wiarygodnych źródeł (data from credible sources). The word appears frequently in journalism, research, and reporting to express trustworthiness or reliability of material.

Related terms: wiarygodność (credibility), wiarygodny (credible/trustworthy), rzetelny (reliable), autentyczny (authentic). While wiarygodny emphasizes trustworthiness, rzetelny often conveys factual reliability and completeness.
