Tiedettyihin

Tiedettyihin is a Finnish grammatical form that illustrates the illative plural of a past passive participle. It combines the participle tiedetty, which denotes being informed or notified, with the illative plural ending -iin. The result is a phrase used to refer to movement into or toward a group of people that is characterized as informed.

Morphology and meaning: The base tiedetty is a past passive participle derived from the idea of having been informed. In Finnish, the illative plural ending -iin attaches to adjectives or participles to express direction into or toward multiple entities. Therefore tiedettyihin functions as an adjective in the illative plural, modifying a following noun in plural form, such as ryhmiin (groups) or henkilöihin (individuals).

Usage context: Tiedettyihin is uncommon in everyday language and is mainly of interest in linguistic discussion or formal demonstrations of Finnish morphology and syntax. It serves as an example of how participles can be inflected for illative case to indicate movement toward a group described by a preceding participle. In typical communication, speakers are more likely to rephrase with a simpler construction, such as “ryhmiin, jotka ovat tiedettyjä” (groups that have been informed).

Examples:

- Tiedettyihin ryhmiin kuuluvat sekä työntekijät että asiantuntijat. (The informed groups include both workers and experts.)

- Kysely lähetettiin tiedettyihin henkilöihin. (The survey was sent to the informed individuals.)
