Aramaic
Aramaic is a Semetic language spoken in much of the Middle East outside the Arabian Peninsula in ancient times. It first entered the region sometime in the 12th century BC and eventually became the major spoken language of Syria, Judea, and Mesopotamia, and along with Greek and (later) Latin, a major language of trade in the Mediterranean. Aramaic was almost certainly the native language of Jesus (Hebrew, by his time, mostly being used for religious purposes by the Jews). Parts of the Old Testament of the Bible were written in Aramaic, as was the Talmud, the main scripture, besides the Torah, of Judaism.
Aramaic retained its importance until the conquest of the Middle East by the Arabs in the 7th and 8th centuries AD. The Arabs made Arabic the dominant language of government, and, over the next several hundred years, most of the population gradually switched to using Arabic as a first language. Aramaic is still spoken by several thousand people in isolated villages in Syria and Iraq.
