Not to be confused with Acadian French or Cajun French. Akkadian (/ÉËkeÉªdiÉn/ akkadÃ», ðððºð ak-ka-du-u2; logogram: ðµð  URIKI ) is an extinct East Semitic language (part of the greater Afroasiatic language family) that was spoken in ancient Mesopotamia.
Situated to the immediate north of Sumer, the Akkadians were of Semitic origin. The people of Mari a little to the north were probably of the same stock. Their language is first attested in about 2800 BC, and it survived alongside Sumerian until about 1800 BC, when the latter died out from everyday use.
