reunustanut

Reunustanut is a Finnish word that functions as the past active participle of the verb reunustaa, meaning to border, edge, or line along the edge with a material such as stone, hedging, or trim. The form indicates that an edging action has been completed by some agent and is often used in descriptive, technical, or landscape-related contexts.

Grammatical notes: As a past participle, reunustanut can form perfect tenses with the auxiliary olla (to have). For example, olen reunustanut pihaa means “I have bordered the yard.” It can also function as an adjective modifying a noun, though such usage is less common in everyday speech. The verb is transitive, taking a direct object representing what is being bordered.

Etymology: The word is built from the noun reuna (edge) with the verbalizing suffix -ustaa and the past participle ending -nut. It shares its morphology with other Finnish past active participles formed with -nut/-nyt.

Usage and frequency: reunustanut is a specialized term. It appears mainly in descriptive writing, landscaping, architecture, horticulture, and certain legal or bureaucratic Finnish where edging or border provisions are discussed.
