Viikoittainen

Viikoittainen is a Finnish adjective meaning "weekly." It is used to describe something that happens once every week or on a weekly basis. The word commonly modifies nouns, for example viikoittainen kokous (a weekly meeting) or viikoittainen julkaisu (a weekly publication). In predicative use, it can describe schedules or patterns, as in Kokous on viikoittainen.

The corresponding adverb is viikoittain, meaning "weekly" in terms of frequency, as in Tapahtuma pidetään viikoittain (The event takes place weekly). The adjective is formed from the noun viikko (week) plus the suffix -ittainen, a common Finnish pattern for creating adjectives denoting regularity or characteristic relates to the base noun.

Usage and nuance: viikoittainen emphasizes the regularity of a weekly occurrence, often in written or formal contexts such as schedules, bulletins, or official descriptions. It contrasts with other time-based forms like kuukausittainen (monthly) or päivittäinen (daily). The distinction between viikoittainen and viikoittain mirrors the general Finnish pattern where adjectives describe the nature of something, while the adverb covers frequency or manner.

See also: kuukausittainen, päivittäinen, vuotuinen. See also viikoittain for adverbial use. Viikoittainen is a standard term in Finnish for describing weekly recurrence in both public notices and everyday language.
