Muodostuvalla

Muodostuvalla is the adessive singular form of the present participle muodostuva, which comes from the verb muodostua meaning “to form” or “to be formed.” In Finnish grammar it functions as an adjective or modifier that describes something in the process of forming or developing. It is commonly used in technical or descriptive language to refer to phenomena, structures, or processes that are still evolving.

Morphology and usage: The present participle muodostuva expresses ongoing formation, and when declined to the adessive case the form becomes muodostuvalla (on/with the forming …). The corresponding nominative form is muodostuva (forming). Other case forms exist for different syntactic roles, enabling the expression of location, manner, or context.

Contexts and examples: Muodostuvalla is typically found in scientific, geological, biological, or industrial texts, and occasionally in descriptive prose that emphasizes change over time. Examples include phrases such as muodostuvalla kerroksella (on the forming layer) or muodostuvalla prosessilla (by/on the forming process). The construction conveys temporality and dynamism, contrasting with the past tense muodustunut (formed) and the present stative muodostuva (forming).

Limitations: The form must agree with the noun it modifies in case and number. It is primarily a modifier and is less common in everyday language outside technical or formal writing. In more general prose, the simple verb forms or other participial constructions may be preferred.
