supplementære

Supplementære is a Norwegian adjective meaning additional, supplementary, or auxiliary. It is used to describe things that are added to what already exists or is required. The word traces back to Latin supplementarius and the French supplémentaire, and it is common in formal and technical language.

In Norwegian, supplementære is typically used before plural nouns and has the base form supplementær. For example: supplementære data, supplementære materialer, or supplementære vinkler. In the definite plural, the form becomes de supplementære dataene, and in other contexts you may see the adjective adjusted to agree with the noun.

The term appears across multiple domains. In mathematics, supplementary vinkler (supplementary angles) are two angles whose measures add up to 180 degrees. In education and publishing, supplementære materialer or supplementær lesning refer to extra readings or resources provided to support the core curriculum. In research, supplementære data are additional datasets that complement the primary data. In law and policy, supplementære bestemmelser or documents serve to augment standard rules or provisions.

Related concepts include tilleggs- (additional) and ekstra (extra). The word is common in technical writing, academic contexts, and formal discourse, where precise augmentation or extension of existing content is described.
