Sumerian Cuneiform is one of the earliest writing systems in the world, developed by the Sumerians around 3200 BCE in ancient Mesopotamia. It consists of wedge-shaped marks made on clay tablets using a stylus. Initially used for record-keeping, it evolved to express a variety of languages and ideas. The system began with pictographs, representing objects or concepts, but gradually transformed into abstract symbols. Cuneiform was used for administrative, legal, and literary purposes, influencing later writing systems. It remained in use for over three millennia, showcasing the importance of written communication in human history.
