renkailla

Renkailla is a Finnish word form that serves as the plural adessive case of the noun rengas, meaning wheel or tire. It is used to express location or instrument, roughly corresponding to the sense “on wheels” or “with wheels.” In descriptive or technical language, renkailla often describes an object that has wheels or is moved by wheels.

Morphology and usage notes: The base noun is rengas; its plural is renkaat. The plural adessive form renkailla is created by taking the plural stem renkaat and adding the adessive suffix -lla. This form appears in catalogs, manuals, and descriptions of wheeled equipment, as well as in sentences that specify a device or vehicle is equipped with wheels or can be moved on wheels. In everyday speech, speakers may choose alternative expressions depending on context, such as using pyörillä for “on wheels” or phrasing the description with varustettu (equipped) to emphasize wheels.

Examples: Laite on renkailla varustettu. The device is equipped with wheels. Kulkuneuvo voidaan siirtää renkailla. The vehicle can be moved on wheels.
