Kuukausina

Kuukausina is a grammatical form of the Finnish noun kuukausi, meaning “months.” It represents the essive plural, a case used to express a temporary state, role, or condition, roughly translated here as “as months” or “in the months.” In practice, kuukausina is used to refer to a time period described in terms of months, and it frequently appears in formal or written Finnish such as reports, agreements, or statistics.

The use of kuukausina can emphasize the months as a unit of time rather than as individual counts. It is more common in official language than in everyday speech, where speakers might prefer other constructions to express duration, such as stating a specific number of months or using a different temporal phrase. The singular counterpart of this form is kuukausena (“as a month”).

Examples:

- Sopimuksen kesto on kuukausina noin kaksikymmentä. (The duration of the contract is about twenty months.)

- Kustannukset jaettiin kuukausina. (Costs were divided into months.)

Related forms include kuukausi in various cases: singular essive kuukausena, plural genitive kuukausien, and partitive kuukausia, among others. The essive plural kuukausina is formed from the stem kuukausi with the -ina suffix, fitting Finnish patterns for essive plural nouns.

In summary, kuukausina is the essive plural form of kuukausi used to describe time periods expressed as months, primarily in formal or written Finnish, and it contrasts with more everyday ways of expressing duration in months.
