Grammatical and Lexical Variation in the Basque Language

The Basque language, without its own administration, has evolved divided intodialects over millennia. Although the standard variety has recently been codified, the regional dialects are still alive. In fact, this wide dialectalization is the object of continuous research and gives us the opportunity to research its variability. The aim of this paper is to examine how geolinguistic variability works in the case of the Basque language. For this purpose, I show some data gathered by using two different procedures. To go deeply into this subject, I focus on the research conducted in two different areas of the Basque language: the first is a study of the geolinguistic structure of the Western dialects, and the second examines the North-Eastern dialects
