Vuosisadalle

Vuosisadalle is a Finnish word that functions as the illative form of vuosisata, meaning century. In Finnish grammar, the illative case expresses direction toward or into a destination, including time periods. Therefore vuosisadalle is used to indicate movement toward or into a century, or to reference entering a new century in narrative, historical writing, or analysis.

Etymology and form: vuosisata is a compound noun formed from vuosi (year) and sata (hundred), together meaning “century.” The illative suffix is applied to the noun to signal “to/into the century,” producing vuosisadalle as the standard form in singular usage. The word appears most commonly in contexts that describe transitions, timelines, or speculative projections related to time.

Usage: Vuosisadalle is encountered in historical discourse and literary narration when a speaker or writer wants to frame events as occurring within or moving into a particular century. It is part of a broader set of Finnish time-related illative expressions and is typically used with verbs expressing movement, progression, or transition.

Related terms: The base form vuosisata refers to the unit “century.” Plural is vuosisadat, and other case forms (such as genitive) use different endings. Finnish time expressions also employ various cases to convey temporal relations beyond the illative.
