Writing is a medium of human communication that involves the representation of a language through a system of physically inscribed, mechanically transferred, or digitally represented symbols. Writing systems are not themselves human languages (with the debatable exception of computer languages); they are means of rendering a language into a form that can be reconstructed by other humans separated by time and/or space.[1][2] While not all languages use a writing system, those with systems of inscriptions can complement and extend capacities of spoken language by enabling the creation of durable forms of speech that can be transmitted.
