Euskera, which is also known under the name of Biscayan in the modern era, is the name given to a non-Indo-European language that is spoken within some territories of Spain and France that are generally found in the vicinity of the Bay of Biscay. This is considered an isolated language, being one of the few languages currently spoken in Europe that does not descend from the Indo-European branch, as is the case with languages such as Finnish, Hungarian, Estonian, Georgian, Turkish and Maltese, being Euskera is the only one present in western Europe.
Euskera, the language of the Basques, is the oldest living language on the European continent. This fact is confirmed by most of the linguists, experts and researchers in this area.
There is no doubt that this is a living and long-standing language whose origin is still unknown today. Linguists of great importance and historians of the same caliber maintain the position of defending the belief that Basque can come directly from the language they spoke, approximately 15,000 years ago the inhabitants of the Altamira, Ekain or Lascaux caves. Its longevity goes back at least to the times of the Neolithic period, despite this there is some evidence that leads to think that the origin of Euskera can be traced even much before this. It is even probable that Basque is one of those responsible for giving rise to articulated language.
Today this Basque language is fully integrated into the educational system of education, within which is the public administration and in the daily life of Spanish society. This is thanks to the fact that in 1978 the Spanish Constitution recognized the official status of this language. However, before this precedent, the language of the Basques was preferably spoken in rural areas and it did not have any grammatical regulations either.
Despite the fact that Euskera is totally different from Spanish or Castilian, it is considered that the vowel use of Euskera has had an influence on the phonetics of Spanish. An example of this are some words in Euskera that have been incorporated into the Spanish vocabulary, such as magpie, coven, cowbell, blackboard, etc.
