todettu

Todettu is a Finnish past participle derived from the verb todeta, meaning to state or declare. In Finnish grammar it functions primarily as a past passive participle and is used as an adjective or as part of a passive predicate to indicate that something has been found, stated, or declared by a source. The basic sense is "found to be true" or "reported" by authorities or evidence.

In everyday and formal use, todettu appears in phrases such as "todetut tulokset" (the verified results) or "todettu virhe" (the identified error). In predicative structures one often encounters "se on todettu oikeaksi" meaning "it has been found to be true" or "it has been deemed correct." The construction "on todettu" expresses a completed evaluation by an unspecified source. In reporting, science, medicine, and law the form helps convey that conclusions or facts have been established by examination or authorities.

Todettu inflects like an ordinary Finnish adjective, changing form to agree with the noun it describes. It is commonly used in written Finnish, news reporting, scientific summaries, and legal documents, where documenting verification is important. Related terms include todeta (to state), todistus (proof), and varmistaa (to confirm).
