Refutation: Koine Greek is literally the 'common language' — the word koine means 'common' — it was a simplified lingua franca spread through Alexander the Great's empire, the exact opposite of an elite dialect

Citing the University of Texas at Austin Linguistics Research Center's introduction to New Testament Greek: Koine Greek was the common language based on Attic Greek, spread throughout Alexander the Great's empire as a simplified, widely accessible tongue. Morphological categories were reduced, sentences simplified. The word 'koine' itself means 'common.' Jim's claim is precisely backwards.
