Viikoiksi

Viikoiksi is a Finnish word formed as the translative plural of viikko, meaning “weeks.” It is used to express a change of state or classification into weekly units, or to indicate a division of time into weeks in planning, scheduling, or reporting. The suffix -ksi marks the translative case, and with viikko it yields viikoiksi.

In practice, viikoiksi appears in sentences such as “Projektin aikataulu jaetaan viikoiksi,” meaning the project timetable is divided into weeks. It can also describe goals, plans, or schedules that are organized by weeks, for example “tavoitteet asetettiin viikoiksi.” The translative form is common when emphasizing a reorganization or categorization of time rather than a continuous duration.

Important grammatical note: viikoiksi does not express a simple duration. Finnish typically uses the partitive or genitive forms for durations (for example kaksi viikkoa, kahden viikon). The translative form is reserved for a sense of becoming or being classified as weeks, not for stating how long something lasts.

Other time-related translatives exist in Finnish, such as päivä -> päiväksi and kuukausi -> kuukaudeksi, illustrating the broader pattern of transforming time units into a new state or category. Viikoiksi thus sits within Finnish grammar as a productive example of the translative case applied to a time unit, specifying a division into weekly segments rather than a linear measure of time.
