The scribes of the Neo-Assyrian bureaucracy had also used Aramaic, and this practice was subsequently inherited by the succeeding Neo-Babylonian Empire (605–539 BC), and later by the Achaemenid Empire (539–330 BC). Mediated by scribes that had been trained in the language, highly standardized "written" Aramaic (named by scholars as Imperial Aramaic) progressively also become the "lingua franca" of public life, trade and commerce throughout the Achaemenid territories. Wide use of "written" Aramaic subsequently led to the adoption of the Aramaic alphabet and (as logograms) some Aramaic vocabulary in the Pahlavi scripts, which were used by several Middle Iranian languages (including Parthian, Middle Persian, Sogdian, and Khwarazmian).
