Viikkoina

Viikkoina is a Finnish word that functions as the plural essive form of the noun viikko, meaning week. In Finnish grammar, the essive expresses a temporary state or role, such as “in the capacity of” or “as.” The singular essive is viikkona, and the plural essive is viikkoina, which translates roughly to “as weeks” or “in weeks.” The form is primarily found in written or formal language and in contexts describing time spans or distributions across multiple weeks.

Morphology and usage notes:

Viikkoina is created from the stem viikko combined with the essive plural suffix -ina/-inä. It contrasts with other cases used with time words, such as viikkoina versus viikoissa (in weeks) or viikkoja (weeks as a partitive). The plural essive is commonly used with numerals or quantifiers to express durations or states across several weeks, such as “useina viikkoina” (over several weeks) or “kolmena viikkoina” (across three weeks), depending on the exact nuance.

Typical contexts:

- Describing durations that span multiple weeks: Hanke eteni useina viikkoina.

- Describing events or processes occurring over several weeks: Koulutus järjestettiin useina viikkoina.

- Narrative or descriptive passages that refer to weeks as a period or frame of reference.

Derived from viikko with the essive plural suffix -ina, aligned with other Finnish plural essive forms such as vuosina (in years) or päivinä (in days).
