Koostumuksellaan

Koostumuksellaan is a Finnish adverbial form meaning "with its composition" or "by its composition". It is used to indicate that a property, effect or distinction arises from the composition of an object, substance or system.

Grammatically, the word is derived from the noun koostumus ("composition") combined with case marking and a third-person possessive suffix, producing a phrase that attributes agency or causation to the composition of the referent. In usage it commonly appears in technical, scientific and commercial contexts where material makeup, ingredients or structural makeup are relevant.

Examples in Finnish:

- "Tuote erottuu kilpailijoistaan koostumuksellaan." (The product differs from its competitors by its composition.)

- "Lääke vaikuttaa nopeasti koostumuksellaan." (The medicine acts quickly because of its composition.)

In style and register, koostumuksellaan is neutral and typical of descriptive prose in reports, reviews and specifications. It often appears in evaluations of materials (chemistry, engineering), food and cosmetics, and in ecological or geological descriptions where the internal makeup explains behavior or properties. Related expressions include koostumukseltaan (meaning "in terms of composition") and koostumus, the base noun.
