Koostumustaan

Koostumustaan is a Finnish noun phrase meaning “its composition” or “its makeup.” It is derived from the noun koostumus (composition) and is used to indicate the internal arrangement or constituent parts of something, with the third-person possessive form marking that the composition belongs to or characterizes the subject of the sentence. The form is most often encountered in formal, technical, or analytical writing.

Usage and context

Koostumustaan appears in discussions of substances, materials, organisms, or systems where precise description of what something consists of is required. In chemistry and materials science it can refer to chemical or elemental composition. In biology or ecology it may describe the makeup of a tissue, organism, or population. In sociology or demography it can be used to discuss the composition of a group or community. Because it is a specific possessive construction, the phrase tends to appear in more formal or technical prose than in everyday speech.

Grammatical notes

The word is formed by combining the root koostumus with suffixes that express possession and case, reflecting Finnish’s agglutinative morphology and vowel harmony. The exact spelling may vary depending on surrounding words and the sentence structure, but the meaning remains “its composition.”
