what writing system did the sumerians invent
The original Sumerian script was adapted for the writing of the Akkadian, Eblaite, Elamite, Hittite, Luwian, Hattic, Hurrian, and Urartian languages, and it inspired the Ugaritic and Old Persian alphabets. Cuneiform writing was gradually replaced by the Phoenician alphabet during the Neo-Assyrian Empire. By the 2nd century C.E., the script had become extinct, and all knowledge of how to read it was lost until it began to be deciphered in the 19th century.
