And the Latin word "evolved" from the Greek.... Certainly the great masters of doxa in Plato's world— the sophists — were in the business of "teaching, showing, and pointing out." The problem — for Plato — was that what they were teaching, showing, and pointing out represented a radical departure from Truth.
Plato was a great literary artist and master of his language — Koine — before anybody even thought to analyze it.
The Greek word to "teach" is not doxa but didasko (that's where Didache comes from).

Koine Greek was spoken vernacular and no one "owned" it, not even Plato, especially since in his days that language did not even exist yet. :)
What you are reading are latter-day copies claiming to be his works written in Koine Greek.
