Reunuksilla

Reunuksilla is a Finnish grammatical form meaning “on the edges” or “at the rims.” It is the adessive plural form of the noun reunus (edge, border, rim) and is used to describe location on multiple edges of an object or feature. The base noun relates to the more common everyday word reuna (edge). In practice, reunuksilla appears in descriptive and technical Finnish to indicate placement or condition along several boundaries.

The word is most often encountered in contexts where precise spatial description is important, such as architecture, design, manufacturing, and technical writing. It helps specify that something is located on, or along, the edges of a component, panel, sheet, or similar item. For example, a sentence might refer to features or finishes that occur on the edges of a plate or panel by saying something about items “reunuksilla.”

Grammatically, reunuksilla follows standard Finnish plural adessive formation, contrasting with other case forms such as reunuksien (genitive), reunuksilla (adessive plural), or reunuksissa (inessive plural). The term is thus not a separate field or concept on its own; rather, it is a case form used to express location relative to multiple edges within Finnish syntax.
