Perusteiksi

Perusteiksi is a Finnish grammatical form used to mean “as bases” or “into bases.” It is the translative plural form of the noun peruste, which translates to foundation, basis, or ground. The translative case expresses becoming or designation into a new state or role, and in this plural form it refers to multiple grounds or criteria that are treated as bases for a conclusion, decision, or classification.

Morphology and formation: The singular translative is perusteeksi, while the plural translative is perusteiksi. This reflects the general Finnish pattern of forming translative forms with the suffix -ksi (singular) or -iksi (plural) appended to the stem, here combined with the plural form of peruste (perusteet) in natural usage.

Usage: Perusteiksi is common in formal, administrative, legal, and academic writing when listing several grounds for a decision, argument, or assessment. It often follows verbs such as asettaa, antaa, nähdä, or käyttää. Examples include: “Nämä havainnot voidaan asettaa perusteiksi päätökselle.” (These observations can be used as grounds for the decision.) and “Hakemuksessa esitetyt seikat muodostavat perusteiksi valinnan tueksi.” (The points presented in the application form the bases for supporting the choice.)

Related terms: The singular form is perusteeksi; related nouns include peruste and perusteet. The concept is often contrasted with perusteet (grounds) rather than used in isolation.
