“Basque” refers to the modern language of Basque spoken in the seven provinces of Euskal Herria from the earliest substantial texts of the 16^th century to the present day.

“Iberian” refers to the apparently seamless continuum of closely related dialects that were spoken throughout the Iberian peninsula and south-western parts of France immediately prior to Romanisation, which probably started at the beginning of the 1^st century BC. The dialects referred to by Vascologists as “Pre-Basque” and “Aquitainian” are “Iberian” under this definition.
