 Mandaic and Assyrian are two (Northwest Semitic) Neo-Aramaic languages that retain some Akkadian vocabulary and grammatical features.Akkadian is a fusional language with grammatical case; and like all Semitic languages, Akkadian uses the system of consonantal roots.The Kültepe texts, which were written in Old Assyrian, include Hittite loanwords and names, which constitute the oldest record of any Indo-European language.
