Euskara Batu Zaharraren haustura: oinarri metodologikoak eta literaturaren berrikuspena

Resumen

It has already been 40 years since Mitxelena (1981) proposed Old Common Basque (OCB) as the last unified language stage before the dialectalization process began. However, Basque diachronic dialectology has not been developed so extensively in these last 40 years and the topic is still very much open to debate. That said, there have been some proposals on the split of OCB. In this paper, I first explore the methods which must be employed to investigate the initial split of OCB based on the best-developed surrounding traditions. Then I review and evaluate works on the initial split of OCB, in order to see whether they fulfill the methodological criteria to make up diachronic dialectology. As one can see, very few works attempt a phylogenetic approach, and even less base their claims on innovations that satisfy chronological, geographical and linguistic criteria.
