nukleäre

Nukleære is a Norwegian adjective meaning nuclear, relating to the nucleus of an atom or, in biology, to the nucleus of a cell. In scientific and technical contexts it is used to describe processes, materials or technologies connected to nuclei and their properties.

In physics and chemistry the term appears in phrases such as nukleære reaksjoner (nuclear reactions), nukleær fisjon (nuclear fission) and fusjon (nuclear fusion), as well as in references to nuclear energy (nukleær energi). In medicine and biology it is used in expressions like nukleærmedisin (nuclear medicine) and when describing cellular structures associated with the nucleus.

Etymology and usage notes: the word is borrowed from French nucléaire, which ultimately comes from Latin nucleus meaning core or kernel. In Norwegian it is commonly used across Bokmål and Nynorsk, with nukleær as the base form and nukleære appearing as the plural or definite form when describing plural nouns, for example nukleære reaksjoner. The term forms part of many technical and academic terms in science and health.

Grammatical notes: nukleær describes nouns related to nuclei and follows standard Norwegian adjective inflection. In practice, the form nukleære is typically used with plural nouns, while the singular indefinite form is nukleær. In compounds and technical usage the root term remains widely understood and standardized in scientific writing.
