Etymology

The word "two-way" is a compound formed by combining "two" (from Old English "twā," meaning the number 2) and "way" (from Old English "weg," meaning a path or direction). The term emerged in the 19th century to describe systems, devices, or interactions that operate bidirectionally, such as two-way streets or two-way communication. The logic is straightforward: "two" emphasizes duality, while "way" specifies the direction or mode of operation.
