uskottavilla

Uskottavilla is a Finnish adjective form derived from uskottava, meaning credible or believable. In usage it often functions in phrases such as uskottavilla perusteilla or uskottavilla todisteilla, where it describes grounds, evidence, or sources as being credible. The expression is common in journalism, analysis, and formal writing to indicate that a claim or conclusion rests on solid, believable foundations.

In grammatical terms, uskottavilla is the plural adessive form of the adjective uskottava. It is used to modify plural nouns in phrases that express basis or grounds, for example uskottavilla perusteilla = on credible grounds. Because Finnish adjectives agree with the noun they modify, uskottavilla appears with plural nouns in the adessive case. The form is typically found in written Finnish rather than everyday speech, and it carries a nuance of measured credibility rather than absolute certainty.

Etymologically, uskottavilla comes from uskottava (credible) and the standard Finnish inflectional ending -lla, which marks the adessive case and plural number. The word belongs to a family of terms related to believability and evidence, alongside uskottavuus (credibility) and luotettavuus (trustworthiness). While related, uskottavilla specifically conveys the aspect of being credible grounds rather than a claim of truth.

See also: uskottavuus, luotettavuus, lähteet, todisteet. In practice, the term signals that statements have credible support, yet it does not guarantee their veracity and should be interpreted in context.
