innenrund

Innenrund is a German term formed from innen (inside) and Rund (circle, round). It is not a single, widely standardized concept, but rather a compound used in varying contexts to refer to inner circular elements or processes. The phrase is typically descriptive rather than a fixed technical term.

In architecture and design, Innenrund can describe an inner circular space or passage within a building, such as a ring corridor surrounding a central area or a circular gallery that sits inside a larger plan. The use is mostly contextual and aimed at conveying the idea of an internal round form rather than naming a distinct architectural category.

In engineering and drafting, the more common expression is innere Rundung (inner rounding) and deals with the interior curvature of a component. This includes specifying a radius that smooths an interior corner or edge. While Innenrund as a standalone noun is uncommon in technical standards, it may appear informally in notes or descriptions to indicate an internal circular feature.

Geographically, Innenrund can occur as a place name or street name in German-speaking regions, reflecting local geography or historical layout. Such toponyms are not widespread and depend on regional naming practices rather than a universal definition.
