koostumuksen

Koostumuksen is the genitive singular form of the Finnish noun koostumus, which translates to composition or makeup in English. As a grammatical form, koostumuksen is used to indicate possession or association, for example in phrases like "koostumuksen osat" (the parts of the composition) or "koostumuksen määrittäminen" (the determination of the composition).

In scientific and technical contexts, the term refers to what a substance or material is made of and in what proportions. Chemists and materials scientists use koostumus to describe chemical or elemental composition, often expressed as a list of components with corresponding percentages, molar fractions, or empirical formulas. Analyses aimed at establishing a material’s koostumus may employ techniques such as spectroscopy, chromatography, or elemental analysis.

Beyond chemistry, koostumus can describe the structure or arrangement of elements within a broader system. In art, literature, or music, it can denote the organizational makeup of a work—how parts such as chapters, movements, or motifs are arranged. In sociology or political science, it may refer to the makeup of a group, organization, or population, emphasizing proportions and roles of its members.

Etymology traces koostumus to the Finnish verb koostua, meaning to consist of, with the noun encapsulating the idea of a built or constitutive makeup. In Finnish dictionaries, koostumus is defined as the arrangement or constitution of something, and koostumuksen is the grammatical form used in possessive constructions.
