1. intersecting line; crossing line

Composed of 交差(こうさ) (crossing, intersection) and (せん) (line). A somewhat technical term used in mathematics, drafting, drawing, and map-reading contexts for lines that cross one another.

Usage

Most often encountered in technical or illustrative contexts — geometry diagrams, technical drawings, architectural blueprints, and art techniques (e.g., crosshatching in pen-and-ink drawing). In casual speech about roads or paths that cross, speakers are more likely to use 交差(こうさ)する as a verb or to refer to the location as a 交差点(こうさてん) (intersection).
