Cuneiform script (/kjuːˈniːᵻfɔːrm/ kew-NEE-i-form or /ˈkjuːnᵻfɔːrm/ KEW-ni-form), one of the earliest systems of writing, was invented by the Sumerians. It is distinguished by its wedge-shaped marks on clay tablets, made by means of a blunt reed for a stylus. The name cuneiform itself simply means "wedge shaped".
Emerging in Sumer in the late fourth millennium BC (the Uruk IV period), cuneiform writing began as a system of pictograms. In the third millennium, the pictorial representations became simplified and more abstract as the number of characters in use grew smaller (Hittite cuneiform). The system consists of a combination of logophonetic, consonantal alphabetic and syllabic signs.
