niezgodny

Niezgodny is an adjective in Polish that denotes a lack of agreement, conformity, or compatibility. It describes something or someone that does not align with another element, rule, standard, or expectation. The word is formed with the prefix nie- attached to zgodni? Actually "zgodny" meaning in agreement or compliant. The corresponding noun is niezgodność, which refers to a discrepancy, nonconformity, or incompatibility.

In use, niezgodny can refer to legal, regulatory, or contractual noncompliance (niezgodny z przepisami prawa, niezgodny z umową), as well as to statements or data that contradict or do not fit with facts (niezgodny z faktami). It can also describe objects, systems, or processes that are incompatible with each other (niezgodny ze standardem). In organizational or interpersonal contexts, it may signal disagreement or opposition to a decision or policy, for example, “to jest niezgodne z oczekiwaniami” or “niezgodny z decyzją władz.” The noun form niezgodność is used for the general concept of nonconformity or discrepancy.

Synonyms and related terms include sprzeczny and niespójny, though each carries its own nuance; sprzeczny often implies logical contradiction, while niezgodny emphasizes nonconformity or noncompliance with rules or norms. In technical language, terms like niekompatybilny are used to express incompatibility in systems or interfaces.

Etymology: the word derives from zgodny (in agreement, compliant) with the negating prefix nie-, and traces back to common Slavic roots for harmony and agreement.
