pyörissä

Pyörissä is a Finnish inessive plural form of the noun pyörä, meaning “in the wheels” or “inside the wheels.” As a location form, it is used to indicate that something is situated within or among the wheels of a vehicle, bicycle, or other wheel-based machinery. In everyday Finnish, the phrase is most common in technical descriptions or mechanical contexts.

Grammatical notes: Finnish expresses location through cases rather than prepositions, and -issä is the inessive plural ending. Therefore pyörissä specifically marks a plural reference to the interior spaces of multiple wheels. The corresponding singular form is pyörässä (in the wheel), and possessive forms such as pyörissäni (in my wheels) can occur when indicating ownership or association.

Usage and examples: Pyörissä often appears in sentences describing components or conditions inside wheel assemblies. For example, “Koneen pyörissä sijaitsevat laakerit ovat kuluneet,” meaning “The bearings located in the wheels have worn out.” Another example: “Käyntien aikana pyörissä oli epäpuhtauksia,” meaning “During operation there were contaminants inside the wheels.” The phrase is primarily used in technical or descriptive prose rather than in casual speech, where simpler formulations like “ pyörien sisällä” or “pyörissä olevat” are more common.

Overall, pyörissä is a specialized locative form that identifies something as being inside or within the wheels of a vehicle or machinery, and it is most meaningful in technical or descriptive contexts.
