tunnetusta

Tunnetusta is the elative singular form of the Finnish adjective tunnettu, meaning known or well-known. The adjective tunnettu is derived from the verb tuntea, “to know,” through the past participle form tunnettu. In Finnish, tunnettu functions like a regular adjective and agrees with the noun it modifies in number and case. The elative form tunnetusta is used to indicate source or origin in relation to what is known, often in formal or written Finnish.

Usage and examples tend to occur in contexts where a statement refers to information, sources, or phenomena that are considered known or established. For instance, tutkimusperinnössä voidaan puhua tunnetusta tutkimuksesta, or more commonly, tutkimuksessa käytetty tieto on peräisin tunnetusta lähteestä, meaning “the information used in the study comes from a well-known/established source.” Another example is Tunnetusta ilmiöstä on kirjoitettu laajasti, meaning “A well-known phenomenon has been written about extensively.”

Relationship to other forms is straightforward: tunnettu has multiple inflected forms, such as tunnetun (genitive) and tunnettua (partitive). Tunnetusta specifically marks elative, indicating “from the known” or “of the known” with a noun in the elative case. The term is primarily a grammatical form typical in descriptive or academic Finnish and does not denote a separate lexical concept beyond the adjective’s normal meaning.
