Perusteta

Perusteta is not a standard lemma in Finnish dictionaries. The verb most commonly associated with the meaning “to establish” is perustaa. If the form perusteta appears, it is typically considered a nonstandard spelling, a typographical error, or a rare dialectal/older variant rather than a recommended modern form. In standard contemporary Finnish, the basic verb and its well-established inflected forms are used instead.

In Finnish, to express that something is being established, the present passive form perustetaan is used (it is established). The past passive form is perustettiin (it was established). The past participle perustettu means “established” and is used in compound tenses or as an adjective, for example: “yritys on perustettu” (the company has been established) or “perustettu yritys” (an established company). The adjective form perustettava means “to be established” or “to be founded,” as in “perustettava yritys” (a company to be established).

Usage notes:

- When you want to say that an institution or organization was created, prefer perustettiin or perustettu, depending on the tense and voice.

- The form perustetaan is used for present-passive statements; perustettiin for past events; perustettu as a participle or in perfect constructions.

- If you encounter perusteta, treat it as nonstandard in modern Finnish and verify against standard forms or consider it a manuscript error.

In sum, perusteta is not a recognized standard form in Finnish; correct usage relies on the standard passive, participle, and related adjective forms derived from perustaa.
