telephone
n. countablen. a piece of equipment you use to talk to people who are in a different place. It sends your voice through wires or radio waves so the other person can hear you.
n. an electronic device or system used for the transmission of sound or speech to a distant point. In modern contexts, it refers to both fixed-line hardware and mobile cellular devices.
The telephone is ringing in the hallway.
Please leave your name and number after the beep so I can return your telephone call later.
Before the advent of digital communication, the telephone served as the primary lifeline for families separated by vast geographical distances, requiring a physical connection to a local exchange.
First used by Alexander Graham Bell in 1876 to refer to the modern instrument, but previous devices had been given this name, which was borrowed from French téléphone. Ultimately from Ancient Greek τῆλε (têle, “afar”) + φωνή (phōnḗ, “voice, sound”).
Often shortened to 'phone' in both spoken and written English.
