päällystettyyn

"Päällystettyyn" is the illative plural form of the Finnish word "päällystetty," which means "coated," "covered," or "lined." The illative case in Finnish indicates movement into or within something. Therefore, "päällystettyyn" translates to "into the coated one(s)" or "within the coated one(s)."

This grammatical form would typically be used in a sentence to describe an action of entering or being situated inside something that is coated or covered. For example, it could be used when discussing entering a coated room, a lined container, or a surface that has been applied with a coating. The specific context would determine the exact meaning.

The word itself is derived from the verb "päällystää," meaning "to coat," "to cover," or "to line." The past participle "päällystetty" describes the state of having been coated. When the illative ending "-än" is added to the plural form "päällystetyt," it becomes "päällystettyihin." However, "päällystettyyn" specifically refers to the illative singular form, meaning "into the coated one" or "within the coated one." It's important to note the distinction between singular and plural forms in Finnish grammar.
