Babylonian Documentary Aramaic

Babylonian Documentary Aramaic is a dialect in use from the 3rd century AD onwards. It is the dialect of Babylonian private documents, and, from the 12th century, all Jewish private documents are in Aramaic. It is based on Hasmonaean with very few changes. This was perhaps because many of the documents in BDA are legal documents, the language in them had to be sensible throughout the Jewish community from the start, and Hasmonaean was the old standard.
