niepewne

Niepewne is the neuter singular form of the Polish adjective niepewny, meaning uncertain, doubtful, or unreliable. The form is used with neuter nouns and, in many cases, with plural noun phrases, while the masculine personal plural form is niepewni. In everyday use, niepewne describes situations, information, or outcomes that lack sufficient confidence or clarity.

Etymology and related forms: the word combines the prefix nie- (a negation) with pewny (certain, reliable). The resulting term conveys a lack of certainty and is closely related to related nouns such as niepewność (uncertainty) and to synonyms like wątpliwy (doubtful) or niejasny (unclear).

Usage and examples: niepewne data or niepewne dane refer to data whose accuracy cannot be guaranteed. Niepewne prognozy describe forecasts with a low level of confidence. In scientific, journalistic, and policy contexts, this form signals caution in interpreting results or making decisions. The term can appear in qualitative assessments as well as in risk evaluations.
