Writing is the act of creating a persistent, visual, static representation of language. A writing system includes a particular set of symbols that are called a script, as well as the rules by which they encode a particular spoken language. Every written language arises from a corresponding spoken language; while the use of language is universal across human societies, most spoken languages are not written.
Writing is a cognitive and social activity involving neuropsychological and physical processes. The outcome of this activity, also called writing (or a text) is a series of physically inscribed, mechanically transferred, or digitally represented symbols. Reading is the corresponding process of interpreting a written text, with the interpreter referred to as a reader.
