Morphology

radiotelephony = radiotelephone (transparent) = radio + telephone + y

Formed by adding the noun-forming suffix '-y' to 'radiotelephone' (itself radio + telephone); the meaning is a straightforward technical extension.

Etymology

Radiotelephony joins radio and telephone: tele- means 'far' and phone means 'sound', so it literally means 'sound sent over distance'. That's why radiotelephony means sending speech by radio waves instead of wires to talk over long distances.
