Polypath

Polypath is a term used in several disciplines to describe a path that is composed of multiple segments or branches rather than a single, unbroken line. The word combines the Greek prefix poly- meaning many with path, signaling multiplicity in the route being described.

In mathematics and computer science, polypath can refer to a path formed by concatenating shorter subpaths. This concept appears in discussions of path decomposition in graphs, network routing, and traversal algorithms, where a longer route is analyzed as a sequence of subpaths. In computational geometry and computer graphics, a polypath is often synonymous with a polyline or a polygonal chain—an oriented curve represented by a series of connected vertices. Many vector and design formats model outlines as paths that may consist of multiple subpaths, enabling complex shapes and disjoint components.

In typography and font design, outlines of glyphs are typically constructed from multiple subpaths. Descriptions of these outlines as polypaths reflect their composition from several joined segments rather than a single continuous stroke.

In narrative theory and media studies, the term polypath is sometimes used rhetorically to describe storytelling that follows multiple intertwined routes or viewpoints, rather than a linear, single-thread narrative. This usage emphasizes multiplicity and interconnectedness of plot lines, though it is less standardized than in geometric or algorithmic contexts.

Overall, polypath is a context-dependent term used to denote multiplicity of path structures, whether in geometry, computation, typography, or narrative form. See also polyline, path, subpath, and path decomposition.
