seinällä

Seinällä is a Finnish locative form derived from the noun seinä (wall) with the adessive singular suffix -llä, indicating location on the surface of a wall. It is used to describe where something is positioned, especially when items are attached to or displayed on a wall.

In everyday language, seinällä is used with verbs of placement such as olla (to be) and kiinnittää or ripustaa (to attach or hang). Examples include taulu on seinällä (the painting is on the wall) and kello on seinällä (the clock is on the wall). The construction can also appear in sentences like Hän kiinnitti hyllyn seinälle (He mounted the shelf on the wall). For plural references, the form seinillä is used to mean on the walls.

Grammatical notes: seinällä marks a surface-location, not an interior position. If something is inside or within the wall, other expressions apply, such as seinässä (inside the wall or within the wall) or seinän sisällä (inside the wall cavity). The form seinällä also integrates naturally with possessive and descriptive modifiers, as in vanha taulu seinällä (an old painting on the wall).

Common usage considerations: Finnish often uses adessive forms like seinällä for surfaces in spatial descriptions, including furniture, pictures, notices, and decorations mounted on vertical surfaces. The plural seinillä corresponds to multiple walls or surfaces where objects are displayed or mounted.
