Interesting turn, there, getting to philately. A word actually derived from telikos would be teleology, or the June 30 word of the day, telic.

Teleology is the study of the evidence of design in nature, in other words and end goal.

The "tele" of telephone is derived from a different Greek root, meaning "far away."

However, AWAD stated, when giving telic as the word of the day: [From Greek telikos, from telos (end). The word telephone comes from the same root.]

How many other such specious etymologies has Wordsmith provided?
