viidennen

Viidennen is the genitive singular form of the Finnish ordinal viides, meaning “the fifth.” In Finnish, ordinals decline like adjectives, and the genitive singular ending -en is used when the ordinal accompanies a noun in genitive or forms certain time expressions.

Typical uses include:

- viidennen kerroksen ovi, meaning “the door of the fifth floor.”

- viidennen kerran, meaning “the fifth time,” used in sentences such as Olen käynyt siellä jo viidennen kerran (“I have been there already five times”).

The form viidennen is therefore a grammatical inflection rather than a standalone noun. It functions to indicate attribution or possessive relation in phrases where the noun is in a genitive case, and it also appears in common phrases counting occurrences, schedules, or levels.

Finnish ordinals such as viides are used across contexts to denote order, dates, floors, rounds, or steps, and their inflected forms align with the case patterns of adjectives in the language. Viidennen, specifically, is the genitive singular form used when the ordinal modifies a noun that is themselves in genitive or when forming time expressions like “the fifth time.”
