The existence of dialects in a heterogeneous society is a natural manifestation of group differences.
Dialects are one of the basic elements of our social organization.
The existence of dialects results from a combination of historical, social and linguistic causes. In the ideal situation for dialect development, both physical and social separation takes place between groups of speakers. One of the most important explanations for the emergence of dialects in America starts with the settlement patterns of the original groups of speakers. These first settlers typically establish a cultural and linguistic area that persists through time, even though certain aspects of their speech will inevitably change. Adjacent land is occupied and settled and the identity of the new culture emerges, as a cohesive society develops in the region.
