Hello Slava and welcome to the board!!

This is a very interesting point that you bring up! I am however, somewhat confused and have a bunch of questions.

1. What is the English prefix, 'tele', derived from? I understand, from your post, that it is NOT 'telos'; is there a Greek 'tele' that the English one derives from and do they both mean, a far distance?

2. You also write that the Greek telos is a noun. The argument then, is probably won here itself. Doesn't it sound like semantic cacophony to have an English *prefix derive from a Greek *noun? Or does it? of troy is * not going to be amused by that hesitant add-on .....

3. *telos* has as its basic meaning "a coming to pass, performance, consummation, result."

Any other words that derive from telos? As I write, two words immediately spring to mind; Telencephalon and Philatelic. Telencephalon (development anatomy term for the part of the forebrain, from which the cerebral hemispheres develop), I can extend to telos; it being the anterior *end of the brain.
Philatelic, if derived from telos, makes no sense at all....
