Kuukausia

Kuukausia is the partitive plural form of kuukausi, the Finnish word for a calendar month. The term kuukausi itself comes from a historical idea of a lunar month, combining kuu (moon) and kausi (season or period). In everyday Finnish, kuukausi denotes a roughly defined unit of time that corresponds to a calendar month, typically ranging from 28 to 31 days depending on the month.

In Finnish grammar, the noun kuukausi has several forms. The nominative plural is kuukauset (months), while the partitive plural form is kuukausia, used when the object is indefinite or when the verb requires the partitive case. For example, useita kuukausia means for several months. The genitive plural is kuukausien, and the partitive singular is kuukautta (for example, kolme kuukautta means three months). This system mirrors Finnish noun declension, where case and number affect the form of the noun.

Usage notes and context: kuukausia appears mainly in phrases describing duration or quantity of months in a non-specific sense, often in relation to ongoing time frames or ongoing actions. It is common in written and spoken Finnish to refer to periods such as employment, study, or project durations using kuukausia.
