Koostuste

Koostuste is the Estonian genitive plural form of the noun koostus, which broadly means composition, mixture, or ingredients. In usage, koostuste denotes “of the compositions” or “of the ingredients,” depending on the sense of koostus in a given context. It appears in writing that discusses multiple components, such as product formulations, recipes, artwork or text analyses, and other descriptions of elemental parts.

Etymology and form: Koostus is formed from the verb koostatama, meaning to compose or put together. The noun koostus carries the meaning of a composition or set of components. Its genitive plural ending is -te, yielding koostuste. This inflected form is used when the relationship is expressed as “of the …” with multiple components.

Usage and contexts: Koostuste is common in technical, scientific, culinary, and descriptive texts where the components of a whole are enumerated or analyzed. It often occurs in noun phrases such as koosteuste nimekiri or koostoeste kvaliteet, where the exact meaning shifts with koostus’ sense (ingredients vs. compositions). The term is primarily a grammatical inflection rather than a standalone concept.

Examples (illustrative): toote koostuste loetelu (the list of a product’s ingredients), koostuste kvaliteet (the quality of the compositions/ingredients), koostuste jaotus (the distribution of components). The precise interpretation depends on the broader context and the accompanying nouns.
