Todistetusta

Todistetusta is a Finnish inflected form of the past participle todistettu, which means "proved" or "evidenced." It is the elative singular form used with a noun in contexts where the source or origin is expressed as coming from something that has been proven or established. In Finnish grammar, such participles behave as adjectives and are declined like other participles to agree with the noun they modify.

Morphology and usage

Todistetusta is formed from the verb todistaa (to prove) plus the participle suffix -ttu and then the elative case ending -sta. As a result, todistetusta typically appears in phrases describing origin, basis, or source information. It functions both attributively (modifying a noun) and, in some syntactic structures, in dependent clauses where a proven condition or fact is being referred to.

Common contexts

In formal or technical writing, todistetusta is used to indicate something that has been demonstrated or supported by evidence. Examples of typical phrases include todistetusta syystä (for a proven/reasoned reason) and todistetusta aineistosta (from the proven data/material). The form is one of several case-inflected derivatives of todistaa that Finnish uses to express nuance about evidence and proof.

Relation to related terms

Todistetusta is closely related to other inflected forms of todistettu, such as todistetun (genitive), todistetussa (inessive), and todistettua (partitive). The base word todistaa connects to nouns like todistus (evidence, proof) and to discussions of proof, verification, and documentation in Finnish.
