samsetningur

Samsetningur is a noun in Icelandic that denotes a composition, construction, make-up, or mixture. The term is used across disciplines to describe how parts are arranged to form a whole. It can refer to a tangible object, a conceptual structure, or the act of combining elements. In everyday use it often means a simple mixture or combination, while in technical contexts it specifies the arrangement or makeup of something.

In linguistics, samsetningur describes the process and product of forming compounds by combining two or more smaller units into a single word, known as samsett orð. In science, it is used for chemical composition—the identity and proportion of elements in a substance. In music and art, it can refer to the composition or arrangement of a work.

Etymology and grammar: the word is formed with the prefix sam- meaning "together" and a root related to setting or placing. It is masculine: nominative singular samsetningur; plural samsetningar. Other cases follow standard Icelandic noun inflection.
