What are the dynamics that run through the spoken and written language? It is often thought that the second is a simple emanation - more formal and planned - than the first, forgetting that most of the languages spoken in the world has never had a written form. And what about today, an era in which the overlap between spoken and written language - think of the use of text messages and social networks - became evident? Is it true that speech as a primary code has now tainted the clarity of the writing? Through historical reports, theoretical references and examples of immediate understanding, Luca Serianni guides the reader on a journey through the different forms that the written text has acquired over time according to the emotions, information and concepts to be conveyed. A dialogue that has never been interrupted between writing and orality, which in recent years - as Giuseppe Antonelli says in his introduction - has given life to the Italian: the Italian typed in new forms of communication.
