Jewish Koine Greek in the context of "Romaniote Jews"

Hellenistic Judaism was a form of Judaism in classical antiquity that combined Jewish religious tradition with elements of Hellenistic culture and religion. Until the early Muslim conquests of the eastern Mediterranean, the main centers of Hellenistic Judaism were Alexandria in Egypt and Antioch in Syria (modern-day Turkey), the two main Greek urban settlements of the Middle East and North Africa, both founded in the end of the 4th century BCE in the wake of the conquests of Alexander the Great. Hellenistic Judaism also existed in Jerusalem during the Second Temple Period, where there was a conflict between Hellenizers and traditionalists.

The major literary product of the contact between Second Temple Judaism and Hellenistic culture is the Septuagint translation of the Hebrew Bible from Biblical Hebrew and Biblical Aramaic to Koine Greek, specifically, Jewish Koine Greek. Mentionable are also the philosophic and ethical treatises of Philo and the historiographical works of the other Hellenistic Jewish authors.

Yevanic, also known as Judaeo-Greek, Romaniyot, Romaniote, and Yevanitika, is a Greek dialect formerly used by the Romaniotes and by the Constantinopolitan Karaites (in whose case the language is called Karaitika or Karaeo-Greek). The Romaniotes are a group of Greek Jews whose presence in the Levant is documented since the Byzantine period. Its linguistic lineage stems from the Jewish Koine spoken primarily by Hellenistic Jews throughout the region, and includes Hebrew and Aramaic elements. It was mutually intelligible with the Greek dialects of the Christian population. The Romaniotes used the Hebrew alphabet to write Greek and Yevanic texts. Judaeo-Greek has had in its history different spoken variants depending on different eras, geographical and sociocultural backgrounds. The oldest Modern Greek text was found in the Cairo Geniza and is actually a Jewish translation of the Book of Ecclesiastes (Kohelet).
