Latin -> Greek -> Semitic -> Akkadian.

Akkadian (lišānum akkadītum, ak.ka.dû) (also Accadian, Assyro-Babylonian) is an extinct Semitic language (part of the greater Afroasiatic language family) that was spoken in ancient Mesopotamia. The earliest attested Semitic language, it used the cuneiform writing system derived ultimately from ancient Sumerian, an unrelated language isolate. The name of the language is derived from the city of Akkad, a major center of Mesopotamian civilization.
