käytyyn

Käytyyn is a Finnish illative singular form of the past passive participle käyty, used as an attributive adjective. The participle käyty derives from the verb käydä, meaning “to go” or “to visit.” When inflected for the illative case, it yields käytyyn, which refers to a noun that designates a destination or place that has already been visited. In this sense käytyyn functions as “visited” or “that has been visited,” and it is most often found in written or formal language.

Usage and characteristics: Käytyyn typically appears with nouns denoting places or destinations, producing phrases such as käytyyn paikkaan (to the place that has been visited) or käytyyn kylään (to the village that has been visited). The form reflects movement into a location in the illative case and agrees with the noun it modifies in number and case. The construction is relatively rare in everyday speech and is more common in literary writing, travel writing, or historical descriptions. For plural referents, the corresponding illative form is käytyihin (to the places that have been visited).

Examples:

- Tutkimus kohdistui käytyyn kylään. (The study focused on the village that had been visited.)

- Käytyyn paikkaan johtaa pieni polku. (A small path leads to the place that has been visited.)

Notes: Käytyyn is a specialized grammatical form and may be unfamiliar to speakers outside formal or descriptive contexts. It illustrates how Finnish uses participles as adjectives and how illative forms combine with participial stems to specify movement into a referenced location.
