todistuksen

Todistus is a Finnish noun with several related senses, most commonly a formal document that confirms a fact or a certificate, or more broadly a proof or testimony. The word’s genitive singular form is todistuksen, which is used to indicate possession or association with the certificate or proof. For example, todistuksen kopio means a copy of the certificate, and todistuksen mukaan means according to the certificate. The plural genitive is todistusten, as in todistusten sisältö “the contents of the certificates.”

In everyday and official language, todistus denotes documents issued by authorities, such as birth certificates, education certificates, employment certificates, or other formal attestations. It is also used in a broader sense to refer to proof or evidence in legal, academic, or logical contexts; in these senses todistus can be close in meaning to todiste, which more strictly means evidence.

The verb todistaa means to prove, certify, or attest, and the related noun todiste refers to evidence or a piece of proof. Distinctions between senses depend on context: a todistus is typically a document, while todistus can also represent a verbal or formal assertion in proceedings. Common compounds include oppilastodistus (school certificate) and virallinen todistus (official certificate).
