Can such a language exist?
The Spanish language was born in Spain out of the prolific womb of Vulgar Latin. When Spain decided to conquer Latin America, they brought their language with them and introduced it to the indigenous peoples.
However, just as the United States of America is geographically cut off from England, producing different intonations, language patterns and phrases, the huge mountain ranges and impenetrable jungle landscapes of Latin America have isolated pockets of Spanish being spoken throughout the region. There is also the same Atlantic Ocean that still separates them all from Mother Spain herself. These geographic barriers produced several dialects of Spanish that sound distinctly different than the Spanish mother tongue. As all languages evolve with time, almost every region of Latin America has a form of Spanish uniquely their own, with some distinctive nouns and phraseology. Other areas that are so cut off from the outer world by nearly insurmountable geographic forces have kept a form of Spanish almost as pure as their Castilian predecessors.
