The word 'teletype' is a modern compound formed in the early 20th century from two classical Greek elements via their English adaptations. The first part, 'tele-', carries the ancient sense of "at a distance," a concept preserved from its Proto-Indo-European root kwel-. The second part, 'type,' derives from the Greek typos, originally meaning the mark of a blow, which evolved through Latin into meanings related to stamping, figure, and later, printed characters. The compound's logic is perfectly transparent: it literally means "distant printing," directly describing a machine for sending typed communications over long distances, a function that evolved from earlier telegraph systems.

Structure: tele (distant) + type (printing) tele: From Greek tēle-, meaning "far off, at a distance." It functions as a combining form indicating operation over a long distance. type: From Greek typos, meaning "a blow, impression, model." In this compound, it refers to the act of printing or striking characters.
