Kombinasjons

Kombinasjons is a stem used in Norwegian to form compound nouns and adjectives related to the concept of combination. The base noun kombinasjon means a joining or arrangement of elements, and kombinasjons- functions as a productive prefix that signals that a term concerns combinations, methods, devices, or analyses involving combinations. As a standalone term, kombinasjons is not commonly used as an independent noun; it appears mainly in compound words.

Etymology and usage

The prefix derives from the Latin combinatio, via French combinaison and related to the English word combination. In Norwegian and other Scandinavian languages, kombinasjons- is employed to create terms that describe things built on or about combinations. Examples of common compounds include kombinasjonslås (combination lock), kombinasjonsberegning (calculation by combinations), and kombinasjonsanalyse (combination analysis). In many scientific and mathematical contexts, the ordinary word kombinasjon (without the -s prefix) is preferred, while kombinasjons- marks a relationship to the broader concept of combinations.

Relation to mathematics

In combinatorics, the concept of combinations refers to selecting elements from a set without regard to order. The number of such combinations is given by the binomial coefficient, written as C(n, k) or "n choose k," with formula C(n, k) = n! / (k!(n−k)!). In Norwegian texts, one might speak of antall kombinasjoner or bruker ofte begrepet kombinasjon i singular, and occasionally use kombinasjons- compounds to describe related methods or analyses.
