viikoittaiseksi

Viikoittaiseksi is a Finnish grammatical form used to express a change of state turning something into a weekly version or schedule. It is the translative form of the adjective viikoittainen, which means weekly. The translative suffix -ksi attaches to the stem to indicate becoming or being declared as something. Therefore viikoittaiseksi is used when stating that a thing has been changed to weekly, or is being designated as weekly.

In usage, viikoittaiseksi appears with verbs of becoming or transformation, such as muuttaa, tehdä, or muuttua. Examples include: Sopimus muutettiin viikoittaiseksi (“The contract was changed to weekly.”) and Tilaus tehtiin viikoittaiseksi (“The order was made weekly”). The form emphasizes a status change rather than merely describing a weekly occurrence.

Distinctions from related forms are subtle. Viikoittainen describes something that is weekly by nature or characteristic. Viikoittain is an adverb meaning “weekly” in the sense of frequency or regular occurrence. Viikoittaiseksi specifically conveys a transition to the weekly form or schedule, often in formal or administrative contexts such as contracts, schedules, or policy documents.

Notes on use: viikoittaiseksi tends to appear in written, formal Finnish and is appropriate in contexts where a change in planning, reporting cadence, or program scheduling is being announced or recorded. It is less common in casual speech, where viikoittain or simply viikottain would be more typical for describing weekly frequency.
