Sisäreunassa

Sisäreunassa is a Finnish locative adverbial form derived from sisäreuna, meaning the inner edge. It describes the position of an object relative to the inside boundary of another object, roughly translating to “on the inner edge” or “at the inner boundary” in English. In Finnish, the suffix -ssa marks location within or on a surface, so sisäreunassa specifies a position along that inner edge.

Etymology and grammar: The base noun sisäreuna combines sisä- ‘inside’ with reuna ‘edge’. The suffix -ssa is the inessive/locative case, indicating location on or within something. The form is used adverbially to describe where something is placed or aligned.

Usage: The term appears in contexts such as carpentry, cabinetry, industrial design, and technical drawings, where precise alignment to the inner edge matters. It can describe both literal placements on an object and metaphorical proximity to an inner limit. Example: “Aseta lista sisäreunaan” (place the molding along the inner edge).
