Aquitanian is generally considered to be either the ancestor of Basque (i.e. Proto-Basque) or a language closely related to it. Its only attestations are given names in otherwise Latin inscriptions. For practical purposes, only attested terms should be categorized as Aquitanian; while reconstructed terms (with or without Aquitanian parallels) should be considered Proto-Basque.

As it stands currently, the coverage of Aquitanian in Wiktionary mostly consists of unsourced reconstructions which are generally identical to Proto-Basque. They should be cleaned up and moved to the corresponding given names in which (Proto-)Basque elements have been identified, preferably with a quotation. For example, compare Nescato with its pre-cleanup version.
