What is a wedge-shaped writing formed in wet clay?

Wedge-shaped writing formed in wet clay is known as cuneiform. This ancient script originated in Mesopotamia around 3200 BCE and was created by pressing a stylus into soft clay to produce triangular-shaped marks. Cuneiform was used for various languages and purposes, including record-keeping, literature, and legal documents, and is considered one of the earliest forms of written expression.
