Writing system

Convention of symbols representing language

A writing system comprises a set of symbols, called a script, as well as the rules by which the script represents a particular language. The earliest writing was invented during the late 4th millennium BC. Throughout history, each writing system invented without prior knowledge of writing gradually evolved from a system of proto-writing that included a small number of ideograms, which were not fully capable of encoding spoken language, and lacked the ability to express a broad range of ideas.
