The word "cuneiform" means "wedge-shaped." It comes from the Latin word "cuneus," meaning wedge. Cuneiform is a writing system characterized by its wedge-shaped marks made by pressing a stylus into clay tablets. This script was originally developed by the Sumerians in ancient Mesopotamia and is one of the earliest known forms of writing. It was used for several ancient languages and involved making wedge-shaped impressions to represent words or sounds.
