käytettyen

Käytettyen is not a standard Finnish word and does not appear in contemporary Finnish dictionaries. In practice, it is generally regarded as a nonstandard form, a potential misspelling, or an archaic/dialectal variant of related forms derived from the verb käyttää (to use). There is no widely accepted grammatical function for käytettyen in modern Finnish, and it is not recognized as a normative inflection.

In standard Finnish, the closest related forms are clearly attested and regularly used:

- käytetty, the past participle meaning "used," typically functioning as a descriptive adjective (käytetty auto = a used car).

- käytettynä, an adverbial/essive-like form meaning “being used” or “in its used state,” and used in various contexts to describe condition or manner.

- käytettyjen, the genitive plural form used to modify a noun in the genitive (käytettyjen autojen = of used cars).

- käytettyinä, the plural essive form meaning “as used [items]” in appropriate constructions (käytettyinä esineinä = as used items).

If käytettyen appears in a text, it is prudent to treat it as nonstandard, likely erroneous, or as a rare dialectal/archaic variant. For clarity and compliance with standard Finnish, it should be replaced with the appropriate standard form according to the syntactic role intended (käytetty, käytettynä, käytettyjen, käytettyinä, etc.).
