Etymology

Origin of telephone

First recorded in 1825–35; tele- 1 + -phone

Explanation

A telephone is an electronic device that you use for conversations over great distances. Telephones used to be fixed to walls and connected by cables, but now most people have cellular telephones, known as cell phones or mobiles. A telephone takes sound waves, converts it into electronic signals, and then converts that back into sound waves — pretty neat. Early telephones frightened people because it seemed spooky that someone not in the room (or even the country) could speak to you, but nowadays distant communication seems perfectly normal. If your mother asks you to telephone her, she wants you to give her a call. The word comes from the Greek words for "afar" (tele-) and "voice"(phone).
