lattioihin

Lattioihin is the illative plural form of the Finnish noun lattia, meaning “to the floors” or “into the floors.” It is used to indicate movement toward or placement into multiple floors.

In Finnish grammar, illative denotes direction toward a destination, and the plural form is typically -iin or -ihin depending on the noun’s stem. For lattia, the standard illative plural form is lattioihin. This form appears in technical and architectural contexts where actions involve floors, such as installation, drilling, or routing.

Common contexts include construction, interior work, and building services, where components or actions are said to be applied to or through the floors. For example, reikiä porattiin lattioihin (holes were drilled into the floors), kaapelit vedettiin lattioihin (cables were run into the floors), or lämmitysputket asennettiin lattioihin (heating pipes were installed into the floors).

Lattioihin is related to lattia (the floor) and to the illatiivi case in Finnish grammar. It is a specialized inflection used in precise technical or descriptive writing rather than everyday speech.
