<P> Koine Greek (UK English / ˈkɔɪniː /, US English / kɔɪˈneɪ /, / ˈkɔɪneɪ / or / kiːˈniː /; from Koine Greek ἡ κοινὴ διάλεκτος, "the common dialect"), also known as Alexandrian dialect, common Attic, Hellenistic or Biblical Greek (Modern Greek: Ελληνιστική Κοινή, "Hellenistic Koiné", in the sense of "Hellenistic supraregional language"), was the common supra - regional form of Greek spoken and written during Hellenistic and Roman antiquity and the early Byzantine era, or Late Antiquity . It evolved from the spread of Greek following the conquests of Alexander the Great in the 4th century BC, and served as the lingua franca of much of the Mediterranean region and the Middle East during the following centuries . It was based mainly on Attic and related Ionic speech forms, with various admixtures brought about through dialect levelling with other varieties . </P> <P> Koine Greek included styles ranging from more conservative literary forms to the spoken vernaculars of the time . As the dominant language of the Byzantine Empire, it developed further into Medieval Greek, which then turned into Modern Greek . Koine remained the court language of the Byzantine Empire until its ending in 1453, while Medieval and eventually Modern Greek were everyday languages . </P> <P> Literary Koine was the medium of much of post-classical Greek literary and scholarly writing, such as the works of Plutarch and Polybius . Koine is also the language of the Christian New Testament, of the Septuagint (the 3rd - century BC Greek translation of the Hebrew Bible), and of most early Christian theological writing by the Church Fathers . In this context, Koine Greek is also known as "Biblical", "New Testament", "ecclesiastical" or "patristic" Greek . It continues to be used as the liturgical language of services in the Greek Orthodox Church . </P> <P> The word koinē (κοινή) is the Greek word for "common", and is here understood as referring to "the common dialect" (ἡ κοινὴ διάλεκτος). The word is pronounced / kɔɪˈneɪ /, / ˈkɔɪneɪ / or / kiːˈniː / in US English and / ˈkɔɪniː / in UK English . The pronunciation of the word in Koine gradually changed from Greek pronunciation: (koinéː) (close to the Classical Attic pronunciation Greek pronunciation: (koinɛ́ː)) to Greek pronunciation: (kyˈni). Its pronunciation in Modern Greek is (ciˈni). </P>
