Explanation:
The system of writing developed by the Sumerians of Mesopotamia is called Cuneiform. It was developed 3500-3000 BCE and is one of the many contributions of the Sumerians. The cuneiform is written by pressing a stylus into soft clay, which produced wedge-like impressions that represent pictographs (word signs), later it represented phonographs. Cuneiform was used by all the great Mesopotamian civilisations . It fell into disuse after 100 BC.
