According to
Koldo Zuazo, there are six main advantages that
euskara batua has brought to the Basque language: • Basque-speakers can easily understand each other when they use
batua. When they use traditional dialects, difficulties in understand one another increase, especially between speakers of non-central dialects. • Before the creation of
batua, Basque speakers had to turn to Spanish or French to discuss modern topics or work subjects: Euskara Batua gives them a suitable tool to do so. •
Batua has made more adult people than ever able to learn the Basque language. • The geographic reach of the Basque language has been in retreat for centuries. Old maps reveal that Basque was formerly spoken in a significantly larger area than today. However, now, thanks to the
euskaltegis and
ikastolas, thanks to primary schools, high schools and universities that teach
batua, the Basque-speaking area is expanding anew, as Basque speakers can now be found in any part of the Basque Country, and at times even outside it. •
Batua has given prestige to Basque because it can now be used in high-level usages of society. • Basque speakers are more united: since
batua was made, the internal boundaries of the language have also been broken, and the sense of being a community is more alive. With a stronger speakers' community, Basque language becomes stronger. All of those advantages have been widely recognised and so have been used by Badihardugu, an organisation supporting the traditional dialects. == Criticism ==
