Orthographic signs (diacritic marks, punctuation marks, and signs and symbols that are part of the Spanish writing system) are the essential pillars of any communicative structure, as they allow it to stand out, and show its solidness and elegance or, if misused, it displays fissures that fail to convey the appropriate content or meaning of the message. In the pages of this book you will find the proper use of the technique of these signs. Each section contains an orthographic sign, its function and its correlation with other signs, as well as the mistakes made by their improper use or the absence of a sign. These rules are not the result of an instant or someone's whim; the omission or misuse of those needed signs at a given moment make the message incomprehensible and the intention of the writer is lost in chaos and misunderstanding.
