Koine Greek
From Textus Receptus
Koine Greek (Greek: Κοινὴ Ἑλληνική, IPA: [ciˈni e̞liniˈci], "common Greek", or ἡ κοινὴ διάλεκτος, [i ciˈni ðiˈale̞kto̞s], "the common dialect") is the popular form of Greek which emerged in post-Classical antiquity (c.300 BC – AD 300). Other names are Alexandrian, Hellenistic, Common, or New Testament Greek. Koine was the first common supra-regional dialect in Greece and came to serve as a lingua franca for the eastern Mediterranean and ancient Near East throughout the Roman period. It was also the original language of the New Testament of the Christian Bible. Koine is the main ancestor of modern Greek.
The term Koine
Koine (Κοινή), Greek for "common", is a term which had been previously applied by ancient scholars to several forms of Greek speech. A school of scholars such as Apollonius Dyscolus and Aelius Herodianus maintained the term Koine to refer to the Proto-Greek language, while others would use it to refer to any vernacular form of Greek speech which differed from the literary language.[1] When Koine gradually became a language of literature, some people distinguished it in two forms: Hellenic (Greek) as the literary post-classical form, and Koine (common) as the spoken popular form. Others chose to refer to Koine as the Alexandrian dialect (Περὶ τῆς Ἀλεξανδρέων διαλέκτου) or the dialect of Alexandria, a term often used by modern classicists.
