The word telemetry is a modern scientific compound built directly from ancient Greek elements. The first part, tele-, carries the core meaning of "distance," a concept traceable to the Proto-Indo-European root kwel-, meaning "far" in time or space. The second part, -metry, derives from metron, meaning "measure," which originates from the PIE root me-, "to measure." Thus, the literal construction "far measurement" perfectly captures the modern technical definition: the science of obtaining measurements from a remote or inaccessible location and transmitting them to receiving equipment for monitoring.

Structure: tele (far) + metry (measurement) - tele: From Greek tēle-, meaning "far off, at a distance." It functions as a combining form indicating distance. - metry: From Greek -metria, meaning "measurement." It functions as a noun-forming suffix denoting the process or science of measuring.
