zag

Zag is the second segment of a zigzag pattern, formed when a line or path repeatedly changes direction at successive angles. In common usage, it describes the movement or design that alternates with a preceding zig, together creating a characteristic sharp, angular path.

Etymology and usage: The word zag appears as part of the compound zigzag, which entered English from German Zickzack. The phrase zig and zag or zigzag has been used since the 19th century to describe alternating turns, lines, or motifs. While "zag" is most often encountered in combination with "zig," it can function as a noun or verb within phrases describing direction changes or decorative patterns.

Applications and contexts: In geometry and drawing, a zigzag or zigzag line consists of connected segments with alternating directions. In sewing and textiles, a zigzag stitch uses a back‑and‑forth pattern to finish edges or provide stretch. In electronics or schematic design, a resistor is sometimes depicted as a zigzag line in certain standard conventions. In navigation, sports, and philosophy, a zigzag or zagging motion may be used to describe detouring, evasive movement, or strategic pathways that differ from a straight course.

Notes: The term zag is largely used within the larger concept of zigzag patterns and movements. Its meaning is context-dependent, often clarified by pairing with zig or by describing the geometric, decorative, or functional application of the pattern. Overall, zag denotes a single backward or alternate segment in a sequence that alternates with zig.
