koostettua

Koostettua is a Finnish grammatical form. It is the partitive singular of the past passive participle koostettu, which comes from the verb koostaa meaning to compose, assemble, or compile. As a participial form used in the partitive case, koostettua describes something that has been composed or compiled, with the object in an indefinite quantity or extent.

In practice, koostettua appears in contexts such as compiled data, texts, or reports. Examples include koostettua aineistoa (compiled material), koostettua tekstiä (assembled text), and koostettua raporttia (compiled report). The partitive usage signals that the material is being referred to in a non-countable or non-specific sense.

Etymology and grammar: Koostettu is formed from the verb koostaa with the suffix -ttu to create the past passive participle. Koostettua is its partitive inflection, used when the noun it modifies is in the partitive case. The base verb and its participle are common in formal and technical Finnish, especially in descriptions of produced or compiled work.

Related terms: The noun kooste denotes a compilation, montage, or summary and is closely related in meaning to koostettu materials, though kooste is often used for a finished, summarized unit. The adjective koottu means gathered or assembled and can be used in similar contexts, usually arising from a different verb stem (koota).

Usage note: Finnish allows alternative expressions depending on nuance and definiteness, such as koottu aineisto or koosteellinen materiaali. Koostettua remains standard when emphasizing the act of compilation and the indefinite extent of the material.
