The Spanish language belongs to the Romance language family and is derived from Latin. It is said that the Spanish language evolved from the Latin language only after the fall of the Romans, and was spoken mainly in the northern region of contemporary Spain. The Spanish language included some characteristics of the Arabic language as a result of the influences from the seven hundred years rule of the Muslim dynasties. Spanish language is also called Castilian by some language specialists who believe that the Spanish language originated in the region of Castalia. King Alfonso VI of Castile was the first monarch to introduce Spanish language in his court. This earlier form of Spanish language was refined mainly through the grammatical corrections in the fifteenth century.

In order to make proper guidelines and regulate the Spanish language, the Royal Spanish Academy was formed in the beginning years of the eighteenth century. It was named the Real Academia Espanola in Spanish. This Spanish language academy was established on the same lines of other European language academies like French and Italian languages. King Phillip V, with the help of the nobles like Duke of Escalona, Marquis of Villena and Juan Pacheco, took the initiative of forming this academy. The basic aim of the Royal Spanish Academy was refinement of the Spanish language improving its vocabulary and evolving a Standard Spanish dialect.

The Royal Spanish Academy drafted the regulations for writing Spanish language and took serious efforts to make it look more elegant than before. Gradually, the regulations and directives of this Spanish language academy in Spain started getting recognition in South American countries, where the Spanish language was the primary language of communication. These countries considered the directives of the Royal Spanish Academy as orders to make changes in its Spanish dialects, and this has been the reason why the written forms of Spanish dialects in these countries are much like the Standard Spanish dialect found in Spain.

The continuous efforts to refine the Spanish language has resulted in the elimination of monosyllabic accented vowels and simplified the form of consonants to simple letters, making the writing form of Spanish language easier than the earlier form. In modern times, there has been a constant conflict of opinion over the exact Standard Spanish dialect, which is mainly between Europe and the American countries. For these reasons, many media companies prefer to use the dialects suitable to specific target market. As a result of these diverse opinions over the exact Standard form of Spanish language, we can find variable Standard Spanish dialect in Spain, Central America, Mexico and the trio South American countries that include Uruguay, Paraguay and Argentina.
