Old Aramaic

Aramaic's long history and diverse and widespread use has led to the development of many divergent varieties, which are sometimes considered dialects, though they have become distinct enough over time that they are now sometimes considered separate languages. Therefore, there is not one singular, static Aramaic language; each time and place rather has had its own variation. The more widely spoken Eastern Aramaic languages are largely restricted to Assyrian, Mandean and Mizrahi Jewish communities in Iraq, northeastern Syria, northwestern Iran, and southeastern Turkey, whilst the severely endangered Western Neo-Aramaic language is spoken by small Christian and Muslim communities in the Anti-Lebanon mountains, and closely related western varieties of Aramaic persisted in Mount Lebanon until as late as the 17th century. The term "Old Aramaic" is used to describe the varieties of the language from its first known use, until the point roughly marked by the rise of the Sasanian Empire (224 AD), dominating the influential, eastern dialect region. As such, the term covers over thirteen centuries of the development of Aramaic. This vast time span includes all Aramaic that is now effectively extinct. Regarding the earliest forms, Beyer suggests that written Aramaic probably dates from the 11th century BCE, as it is established by the 10th century, to which he dates the oldest inscriptions of northern Syria. Heinrichs uses the less controversial date of the 9th century, for which there is clear and widespread attestation.

The central phase in the development of Old Aramaic was its official use by the Neo-Assyrian Empire (911–608 BC), Neo-Babylonian Empire (620–539 BC), and Achaemenid Empire (500–330 BC). The period before this, dubbed "Ancient Aramaic", saw the development of the language from being spoken in Aramaean city-states to become a major means of communication in diplomacy and trade throughout Mesopotamia, the Levant, and Egypt. After the fall of the Achaemenid Empire, local vernaculars became increasingly prominent, fanning the divergence of an Aramaic dialect continuum and the development of differing written standards.
