'Telephone', 'television', and 'telescope' all start with the Greek root 'tele-'. What does that root actually mean, and how does it connect these three words?
- 'Tele-' means 'picture', reflecting that all three devices are designed to display an image.
- 'Tele-' means 'far' or 'distant', reflecting that each device sends sound, images, or a view across a distance.
- 'Tele-' means 'electric', reflecting that all three devices run on electrical power.
- 'Tele-' means 'wire', coming from the copper wire used in early telephone lines.
Why B? And why not the others?
Correct answer: B. 'Tele-' means 'far' or 'distant', reflecting that each device sends sound, images, or a view across a distance.
The Greek word 'tele' meant 'far off' or 'at a distance', and that root shows up across a whole family of invention names that were all built to overcome distance in some way: the telephone carries sound over a distance, the television carries a moving picture over a distance, and the telescope (literally 'far-seeing', combining 'tele' with the Greek for 'to view') lets you see something that is physically far away as if it were close. Once you know the root means 'distance', it also unlocks other 'tele-' words like 'telegraph' (writing sent over a distance) and 'telepathy' (feeling sensed over a distance). 'Picture' is wrong because a telephone carries no picture at all. 'Electric' is wrong because plenty of electric devices with no connection to distance don't use the root, and a telescope isn't electric in the first place. 'Wire' is wrong because the root long predates telephone wires — the Ancient Greeks used 'tele' centuries before electricity existed, and a telescope has never needed a wire at all.
