Who facilities the spread of Sumerian language?

The spread of the Sumerian language was primarily facilitated by the Sumerians themselves through trade, cultural exchange, and the establishment of city-states in ancient Mesopotamia. As one of the earliest known written languages, Sumerian was used in administrative, religious, and literary contexts, which helped propagate its use. Additionally, the influence of neighboring cultures and the adoption of Sumerian by subsequent civilizations, such as the Akkadians, further contributed to its dissemination. Ultimately, the Sumerian language became a foundational element of Mesopotamian culture and education.
