käydyissä

Käydyissä is the inessive plural form of the Finnish past passive participle käyty, derived from the verb käydä. It functions as an attributive participle meaning “visited” and is used to describe plural nouns in the inessive case, for example käydyissä kohteissa = in the visited sites.

Formation and agreement: the base participle käyty takes the inessive plural ending -issä when it modifies a plural noun in the inessive, as in käydyissä museoissa, käydyissä kohteissa, or käydyissä paikoissa. The participle agrees with the noun it modifies in number and case, and it typically appears before the noun it describes.

Usage: käydyissä is common in written Finnish for lists or descriptions that refer to places or things that have already been visited. It emphasizes the visitation status rather than detailing who performed the visit. It is frequently found in travel writing, field reports, inventories, and research summaries that enumerate locations that have been visited.

Notes: käydyissä is primarily used attributively. Predicative use is rare or awkward in standard Finnish; speakers usually use other constructions to express that something is visited or has been visited. The form is part of a broader pattern in Finnish where past passive participles combine with case endings to form adjectival phrases describing previously acted-upon nouns.

Related forms include käyty (the singular past participle) and other participial variants such as käytyjä, käydyissä, or käydyissä-kohteiden kaltaiset ilmaukset, depending on number and case of the noun involved.
