Kreuzung

Kreuzung is a German noun meaning crossing or junction. It derives from Kreuz 'cross' and the nominalizing suffix -ung. The term is used in several fields to denote a point at which two or more lines meet or cross.

In road traffic, a Kreuzung is an at-grade junction where roads cross. Common forms include four-way intersections, T-junctions, and Y-junctions. At these points, traffic rules and controls govern who has priority. In Germany, priority rules such as rechts vor links apply at unsignaled intersections, and signs or signals may assign Vorfahrt. Pedestrian and cyclist crossings are often integrated.

In biology and agriculture, Kreuzung denotes crossing of two individuals or varieties to produce offspring with new trait combinations. This includes intra-specific crosses (within the same species) and interspecific crosses (between species). In botany, horticulture, and animal breeding, Kreuzung is a standard term for hybridization.

Other uses include crossing of railway lines, waterways, or utility routes, as well as metaphorical uses indicating a crossing or convergence of ideas, cultures, or paths.
