Perustetta

Perustetta is the partitive singular form of the Finnish noun peruste, which in general means basis, foundation, justification, or reason. The partitive form is used in sentences that express an indefinite amount or when the noun functions as the object of a verb or a negation.

In everyday and formal Finnish, peruste refers to what justifies a claim, decision, or action. Examples of typical meanings include the grounds for a statement, the rationale behind a rule, or the foundation of a decision. The partitive singuliar perustetta appears in phrases such as “perustetta ei ole” (there is no basis) and “tälle väitteelle ei ole perustetta” (there is no basis for this claim). The plural form is perusteita in the partitive, as in “perusteita” for multiple grounds or reasons.

Etymology and related forms: Peruste is related to verbs such as perustaa (to establish) and perustaminen (establishment). It is part of a family of words describing bases or foundations, including the corresponding adjective form perusteellinen (based on justification). The term is commonly used across legal, administrative, educational, and journalistic language, as well as in everyday speech.

Usage notes: Perustetta is typically used when the statement refers to an indefinite or non-countable amount of justification, or when paired with verbs and constructions that require partitive. For more concrete counts of grounds, Finnish often uses the plural, as in perusteita, whereas singular instances may use perustetta in the right grammatical context.
