The Vasconic languages (from Latin vasco 'Basque') are a putative family of languages that includes Basque and the extinct Aquitanian language. The extinct Iberian language is sometimes putatively included.
The concept of the Vasconic languages is often linked to the Vasconic substratum hypothesis of Theo Vennemann, who speculated that the ancestors of the Basque spread across Europe at the end of the last glacial period when the Cro-Magnons entered Europe and left traces in the modern languages of Europe. Along with other hypotheses that seek to relate Basque to other languages of the world, this is widely rejected by historical linguists.
Proponents of a Vasconic language family argue that Basque and the extinct Aquitanian language are close relatives, or that the modern varieties of Basque are distinct languages rather than dialects. However, these notions contradict conventional views on these languages, in two areas:
Various attempts have been made to tie other languages, modern or extinct, such as Iberian, the language of the Nuraghe, and the language of the Cantabri and various others to Vasconic. None of these theories have been able to provide convincing data, and they are rejected by most mainstream Basque linguists.
A reconstruction of a Proto-Vasconic language is almost impossible with currently available information. More data and research are needed to reconstruct the basics of a proto-language, as well as more information surrounding the neighboring extinct languages such as Iberian and the relationship it has with Vasconic. Reconstruction of a hypothesized Vasconic Proto-language could only be done using the comparative method, although the accuracy of the reconstructed proto-language would still be uncertain.
