Standard Basque

Heavily based on the literary tradition of the central areas (Gipuzkoan and Lapurdian dialects), it is the version of the language that is commonly used in education at all levels, from elementary school to university, on television and radio, and in the vast majority of all written production in Basque.

Having been for centuries pressured by acculturation from both Spanish and French, and particularly under the rule of Franco in which the Basque language was prohibited and came closer to extinction in Spain, the Academy felt the need to create a unified dialect of Basque, so that the language had a greater chance of survival.

The 1968 Arantzazu Congress took place in the sanctuary of Arantzazu, a shrine perched in the highlands of Gipuzkoa and a dynamic Basque cultural focus, where the basic guidelines were laid down for achieving that objective in a systematic way (lexicon, morphology, declension and spelling).

a "plastified Euskeranto",[20][21] as it is at times hardly mutually intelligible with the dialects at the extremes (namely the westernmost one or Biscayan, and the easternmost one or Zuberoan).

Others argue that standard Basque has safeguarded the future of a language that competes with French and Spanish.

Research by the Euskaltzaindia shows that Basque is growing most in the areas where euskara batua has been introduced and taught in preference of local dialects.

Federico Krutwig also promoted the creation of an alternative literary dialect, this time based on the Renaissance Labourdine used by Joanes Leizarraga, the first translator of the Protestant Bible.

Secondly, it has eliminated the (sometimes serious) obstacles that previously existed in communication between speakers from different areas of the Basque Country.
