Part of speech: noun

Definitions

1. The sending of spoken messages over radio waves between transmitters and receivers, especially for aviation, shipping or military use
2. Voice communication carried out by means of radio signals rather than wires, used in aircraft, ships and emergency services
3. The technique or practice of transmitting speech electronically through radio, enabling two-way talk across long distances

Etymology: Telephony, the art or technology of transmitting speech over a distance, was coined from the Greek "têle" (far off) and "phōnē" (voice, sound). Adding "radio-" to it produced a term for wireless telephone communication, in which speech travels by radio waves rather than along wires. The "radio" part comes from Latin "radius," meaning a ray or spoke of a wheel, and it reached English through the scientific vocabulary of electromagnetic waves. The "tele-" and "phone" pieces reveal how the word was built from parts that already existed. "Têle" means far or at a distance, the same element that appears in "telescope" and "television," while "phōnē" gives us "phone," "phonetic," and "symphony." Put together, the word describes voice carried across space, and "radio-" simply specifies the wireless medium. The suffix "-y" turns the noun "telephone" into a name for the activity or system itself, much as "geography" names the study of the earth. The result is a formal, technical word, more common in engineering and military or aviation contexts than in everyday speech, where people just say "radio" or "phone."
