Arvioilla

Arvioilla is the adessive plural form of the Finnish noun arvio, which means estimate, assessment, or opinion. The form literally means “on the estimates” or “by means of estimates” and is used to indicate that something is based on estimates rather than exact measurements. In practice, arvioilla signals that the presented information is provisional or approximate and derives from estimates rather than direct data. The more common construction to express a source as estimates is arvioiden mukaan (according to the estimates); arvioilla tends to appear in technical or formal prose where multiple estimates are cited or when listing sources of uncertainty.

Grammatical notes: arvio is declined in the adessive case as arviolla (singular) and arvioilla (plural). The root of the word is arvio-, and the related verb is arvioida, meaning “to estimate.” Arvioilla is distinct from other forms such as arvioiden mukaan, which marks the estimates as the basis for a statement.

Usage and contexts: The term is frequently found in financial planning, statistical reporting, demographic projections, and policy documents where outcomes are not exact and rely on estimates. It may appear in sentences describing methods, assumptions, or ranges derived from estimations. In everyday Finnish, speakers more commonly use phrases like arvioiden mukaan to attribute conclusions to estimates; arvioilla tends to be reserved for more formal or technical discourse involving several estimates or stated uncertainties.
