The Royal Academy Spanish, also known by its acronym SAR, is one of 23 schools that make up the Association of Spanish Language Academies, located in each of the countries where the Spanish language is spoken, and are responsible for the corresponding linguistic normalization. This important language institution was created in 1713 by the enlightened Juan Manuel Fernández, with its headquarters in Madrid, Spain. The main activity of this is related to the issuance of certain regulations on the standardized use of the Spanish language, so that it has general rules in most of the aspects that compose it.

Around the year 1711, France, Portugal and Italy were among the countries that had dictionaries, books in which they collected information on the terms that made up their own languages, in addition to establishing regulations on their use. Spain, in view of this, decided to get to work and make its own dictionary; that of the Spanish language. Juan Manuel Fernández, a man with different royal titles, is the man who took the earliest initiative to create the institution, taking as reference the Italian Accademia della Crusca and the French Academy. After the first sessions, held in the house of the Marquis of Villena, Felipe V, the then king, decided to take her under his protection.

Over the years, the influence of this was consolidated, even considered the highest authority in the linguistic few rules are concerned. This has been achieved with the publication and regular edition of the DRAE, or dictionary of the Royal Spanish Academy, where the definitions of a lot of terms and some of the most important rules of the language, as well as grammar book are collected in which a specified set of rules for writing and classification of words. Notably, the SAR after the independence of Latin American countries, it urged the creation of several national academies, thus being composed the Association of Spanish Language Academies.
