The term "online" emerged in the mid-20th century, combining "on" (indicating active state or connection) and "line" (referring to telecommunication or data pathways). Originally used for telegraph and telephone systems, it evolved with computing to describe real-time network connectivity. The morpheme "line" traces back to Latin linea (thread, string), reflecting the concept of a linked pathway.
