runkoihin

Runkoihin is a Finnish illative plural form of the noun runko, which broadly refers to a frame, chassis, or main structure of a vehicle, machine, building, or organism. In technical and industrial texts, runko describes the rigid skeleton that supports components and defines the overall shape of an object. The form runkoihin specifically indicates movement toward or placement into multiple frames or frame-like structures, and is commonly used in contexts of assembly, modification, or integration.

In usage, runkoihin appears mainly in engineering, manufacturing, construction, robotics, and related disciplines. It denotes actions where components are added, installed, or organized inside frame structures. Because it carries a precise, technical nuance, runkoihin is less common in everyday language and is most appropriate when describing assembling processes or design steps.

Examples (illustrative):

- Asennuksen aikana komponentit kiinnitettiin runkoihin. (During installation, the components were mounted to the frames.)

- Koneen runkoihin lisäosia kiinnitettiin uudelleenmuotoilun yhteydessä. (The machine’s frames were re-equipped with additional parts during the redesign.)

Related terms include runko (frame or body) and various case forms (genitive, partitive, etc.) used to describe other grammatical relations. In practice, runkoihin is a specialized form best encountered in technical writing, manuals, and design documentation, where precise references to frame-level assembly are required.
