Källkropp

Källkropp (source body) is a Swedish term used in technical and academic contexts to denote the originating body or entity in a system, model, or discourse. The word is a closed compound formed from käll, meaning source or origin, and kropp, meaning body. Because it is a general term, its exact meaning depends on the context.

In science and engineering, källkropp may refer to the physical object that acts as the source of energy, radiation, or matter in a problem, such as the body that emits light or particles in a simulation. In information science and signal processing, it can denote the object or entity from which a signal originates. In the humanities and philosophy, the term can be used metaphorically for the origin of a claim, idea, or event.

The concept is distinct from the recipient or observer in analyses, and from terms describing the effect or result. Källkropp is most common in formal or technical Swedish writing, and typical publications keep it within engineering, physics, or theory discussions.
