Here is the comment I received from a Professor of Greek in the US:

The Greek *tElou* and *tEle* "far away" cannot be DERIVED FROM *telos* meaning "end, goal,* etc.

Any imagined derivation of *tElou" or *tEle* from a supposed datival usage of *telos* meaning "at the end" is simply imaginary.

To start with, the quality of the first vowel is wrong since *tElou, tEle* have eta (a long vowel) in the first syllable while *telos* has an epsilon (a short vowel) in the first syllable.

Second, *telos* has a different semantic field. It is related to *tellesthai* and *tellein*. These are the passive form (*telesthati* = "to come to pass") and the active form (*tellein* = "to accomplish") of the same verb. Thus the noun *telos* has as its basic meaning "a coming to pass, performance, consummation, result."

This would seem to me to be a fairly thourough refutation of AWAD's assertion, but AWAD has not issued a rebuttal or a correction as yet.

I'm trying several Word sites to see if anyone can support AWAD's etymology, but so far no one has.
