Tapahtumisiin

Tapahtumisiin is a Finnish noun-form derived from tapahtuma, meaning “event.” It appears as a plural inflection with the suffix -isiin and has historically been used in some dialects and older texts to convey ideas related to movement toward or into a group of events. In contemporary standard Finnish, the usual illative plural form for “to events” is tapahtumiin, so tapahtumisiin is regarded as archaic, dialectal, or literary rather than common in everyday prose.

Etymology and form: The base is tapahtuma with a plural inflectional ending that resembles other Finnish case endings in the illative or related plural forms. The exact labeling of the case can vary among grammars; some describe it as a historical or regional variant of the illative or a broader plural-inflection pattern, while others treat it as a poetic or nonstandard form.

Usage and distribution: The form occurs primarily in historical writings, poetry, or regional speech, where older or nonstandard inflection patterns persist. In current standard Finnish usage, it is typically replaced by forms such as tapahtumiin, depending on the intended meaning and syntactic construction.

Comparison with standard forms: For expressing “to events” in modern Finnish, most speakers would use tapahtumiin. Tapahtumisiin is not common in formal writing and may appear to readers as archaic or stylistically marked.
