ancient languages were mostly exonymic. In ancient Greek, Aramaic language was most commonly known as the "Syrian language", in relation to the native (non-Greek) inhabitants of the historical region of Syria. Since the name of Syria itself emerged as a variant of Assyria, the biblical Ashur, and Akkadian Ashuru, a complex set of semantic phenomena was created, becoming a subject of interest both among ancient writers and modern scholars. The Koine Greek word (Hebraïstí) has been translated as "Aramaic" in some versions of the Christian New Testament, as Aramaic was at that time the language commonly spoken by the Jews. However, is consistently used in Koine Greek at this time to mean Hebrew and (Syristi) is used to mean Aramaic. In Biblical scholarship, the term "Chaldean" was for many years used as a synonym of Aramaic, due to its use in the book of Daniel and subsequent interpretation by Jerome. Geographic distribution During the Neo-Assyrian and Neo-Babylonian Empires, Arameans, the native speakers of Aramaic, began to settle in greater numbers, at first in Babylonia, and later in Assyria (Upper Mesopotamia, modern-day northern Iraq, northeast Syria, northwest Iran, and southeastern Turkey (what was Armenia at the time). The influx eventually resulted in the Neo-Assyrian Empire (911–605 BC) adopting an Akkadian-influenced Imperial Aramaic as the lingua franca of its empire. This policy was continued by the short-lived Neo-Babylonian Empire and Medes, and all three empires became operationally bilingual in written sources, with Aramaic used alongside Akkadian. The Achaemenid Empire (539–323 BC) continued this tradition, and the extensive influence of these empires led to Aramaic gradually becoming the lingua franca of most of western Asia, Anatolia, the Caucasus, and Egypt. Beginning with the rise of the Rashidun Caliphate in the late 7th century, Arabic gradually replaced Aramaic as the lingua franca of the Near East. However, Aramaic remains a spoken, literary, and liturgical language for local Christians and also some Jews. Aramaic also continues to be spoken by the Assyrians of Iraq, northeastern Syria, southeastern Turkey and northwest Iran, with diaspora communities in Armenia, Georgia, Azerbaijan and southern Russia. The Mandaeans also continue to use Mandaic Aramaic as a liturgical language, although most now speak Arabic as their first language. There are still also a small number of first-language speakers of Western Aramaic varieties in isolated villages in western Syria. Being in contact with other regional languages, some Aramaic dialects were often engaged
