Aramaic alphabet

The ancient Aramaic alphabet was adapted by Arameans from the Phoenician alphabet and became a distinct script by the 8th century BC. It was used to write the Aramaic languages spoken by ancient Aramean pre-Christian tribes throughout the Fertile Crescent. It was also adopted by other peoples as their own alphabet when empires and their subjects underwent linguistic Aramaization during a language shift for governing purposes—a precursor to Arabization centuries later—including among Assyrians who permanently replaced their Akkadian language and its cuneiform script with Aramaic and its script, and among Jews (but not Samaritans), who adopted the Aramaic language as their vernacular and started using the Aramaic alphabet even for writing Hebrew, displacing the former Paleo-Hebrew alphabet. (The modern Hebrew alphabet derives from the Aramaic alphabet, in contrast to the modern Samaritan alphabet, which derives from Paleo-Hebrew). The letters in the Aramaic alphabet all represent consonants, some of which are also used as matres lectionis to indicate long vowels. The Aramaic alphabet is historically significant since virtually all modern Middle Eastern writing systems can be traced back to it. That is primarily due to the widespread usage of the Aramaic language after it was adopted as both a lingua franca and the official language of the Neo-Assyrian and Neo-Babylonian Empires, and their successor, the Achaemenid Empire. Among the descendant scripts in modern use, the Jewish Hebrew alphabet bears the closest relation to the Imperial Aramaic script of the 5th century BC, with an identical letter inventory and, for the most part, nearly identical letter shapes. By contrast the Samaritan Hebrew script is directly descended from Proto-Hebrew/Phoenician script, which was in turn the ancestor of the Aramaic alphabet. The Aramaic alphabet was also an ancestor to the Nabataean alphabet, which in turn had the Arabic alphabet as a descendant.
