Kuukaudeksi

Kuukaudeksi is a Finnish adverbial form meaning “for a month” or “into a month.” It is used to express the duration of something that lasts about one month, or to indicate a temporary state or change lasting that period.

Grammatically, kuukaudeksi is the translative form of the noun kuukausi. In Finnish, the suffix -ksi (translative) marks a change of state or a temporary condition, often tied to time expressions. The form kuukausi + -eksi yields kuukaudeksi. It is typically used after verbs of staying, working, studying, moving, or participating, to specify a one-month duration.

Common usage is to describe temporary arrangements or assignments:

- Asun kuukaudeksi ulkomailla. (I will live abroad for a month.)

- Koulutus kestää kuukaudeksi. (The training lasts for a month.)

- Hän lähti kuukaudeksi lomalle. (He left for a month’s vacation.)

- Osallistun kurssille kuukaudeksi. (I will participate in the course for a month.)

Notes:

- Kuukaudeksi contrasts with other Finnish time forms such as kuukaudessa (in a month), kuukausi (a month), or kuukautta (partitive/genitive forms related to “month” in different grammatical cases).

- The word is neutral in tone and widely used in everyday Finnish, as well as in formal writing when specifying a one-month duration.
