What does the greek telescope mean?

The word "telescope" doesn't come from Greek, it's a combination of Greek roots. It's a modern word, coined after the invention of the telescope.

* Tele (τηλε): Means "far" or "distant."

* Scope (σκοπεῖν): Means "to look" or "to see."

Therefore, "telescope" literally means "far-seeing" or "to see far."
