Have you ever used a radiophone?

No, I haven't! What is it like?

Root Explanation

Radiophone → It is formed from "radio" (from Latin *radius*, meaning ray or beam) and "phone" (from Greek *phone*, meaning voice or sound). The word "radiophone" refers to a device that transmits sound through radio waves, essentially a voice carried by rays.

Memory Tip

Think of 'rays' ('radius') carrying 'sound' ('phone') through the air — that's how a radiophone works.
