Vahvistetun

Vahvistetun is the genitive singular form of the Finnish past passive participle vahvistettu, which means “confirmed” or “validated.” It is a grammatical form rather than a standalone lexical item and is used to modify a noun within a larger noun phrase.

In Finnish, vahvistettu is formed from the verb vahvistaa (“to confirm/validate”) with the participial suffix -ttu. The base form vahvistettu is used in the nominative, while vahvistetun is the genitive singular, indicating possession or association with another noun. The form is common in official, legal, and administrative language where a noun phrase requires the modifier to agree with the head noun in case.

Usage and examples:

- vahvistetun henkilöllisyyden todistus, meaning “the certificate of verified identity.”

- vahvistetun todistuksen kopio, meaning “a copy of the verified certificate.”

These examples illustrate how vahvistetun functions as a modifier in front of a noun in genitive.

Related forms include vahvistettu (nominative) and other participial variants that align with Finnish case and number. While vahvistetun is primarily a grammatical form, it appears frequently in formal texts, certificates, and administrative documentation to convey that certain information or documents have been validated.

Note: As a form, vahvistetun does not convey new semantic content by itself; its meaning derives from the base adjective vahvistettu and the noun it modifies.
