Bögen

Bågen is a term in Swedish and Norwegian that functions as the definite form of the noun båge, meaning arc, bow, or a curved element. The word is used across several domains to denote a curved shape or boundary produced by part of a circle or ellipse, or, more generally, any arch-like form.

In geometry and mathematics, bågen refers to an arc: the portion of a circle between two endpoints. Its properties are defined by the circle’s radius and the central angle, and it is distinct from the chord that directly connects the endpoints.

In architecture and structural design, bågen commonly denotes an arch or curved structural element, such as an arched doorway, a vaulted ceiling, or a curved beam. The term appears in architectural drawings and descriptions to specify curved components.

In nautical and mechanical contexts, the meaning aligns with the general sense of a curved form rather than the vessel’s bow; however, some contexts may describe curved parts of ships or equipment using båge or bågen.

In everyday language, the term is primarily used in technical or descriptive contexts; more common equivalents in English would be arc, arch, or bow, depending on the sense.
