History of writing
The history of writing is primarily the development of expressing language by letters or other marks and also the study and description of these developments.In the history of how systems of representation of language through graphic means have evolved in different human civilizations, more complete writing systems were preceded by proto-writing, systems of ideographic and/or early mnemonic symbols. True writing, in which the content of a linguistic utterance is encoded so that another reader can reconstruct, with a fair degree of accuracy, the exact utterance written down is a later development. It is distinguished from proto-writing which typically avoids encoding grammatical words and affixes, making it more difficult or impossible to reconstruct the exact meaning intended by the writer unless a great deal of context is already known in advance. One of the earliest forms of written expression is cuneiform.
