Sumerian is the language of ancient Sumer and a language isolate that was spoken in Mesopotamia, during the 3rd millennium BC.

Cuneiform is a system of writing first developed by the ancient Sumerians of Mesopotamia c. 3500-3000 BCE. It is considered the most significant among the many cultural contributions of the Sumerians and the greatest among those of the Sumerian city of Uruk which advanced the writing of cuneiform c. 3200 BCE.

In cuneiform, a carefully cut writing implement known as a stylus is pressed into soft clay to produce wedge-like impressions that represent word-signs (pictographs) and, later, phonograms or `word-concepts' (closer to a modern-day understanding of a `word').
