Paleohispanic languages

The paleo-Hispanic languages are the languages of the Pre-Roman peoples of the Iberian Peninsula, excluding languages of foreign colonies, such as Greek in Emporion and Phoenician in Qart Hadast. After the Roman conquest of Hispania the Paleohispanic languages, with the exception of Proto-Basque, were replaced by Latin, the ancestor of the modern Iberian Romance languages.

Languages
Some of these languages were documented directly through inscriptions, mainly in Paleohispanic scripts, that date for sure between the 5th century BC, maybe from the 7th century in the opinion of some researchers, until the end of the 1st century BC or the beginning of the 1st century AD.
 * Vasconic languages
 * Proto-Basque — Unattested, partially reconstructed through internal analysis of modern Basque. Proto-Basque is also the ancestor or sibling of the Aquitanian language (see below).
 * Aquitanian — Close relative of modern Basque. Some scholars characterise Aquitanian as an ancestor of Basque, while others describe Aquitanian and Basque as siblings both descended from Proto-Basque.
 * Unclassified languages
 * Iberian — Shares many obvious similarities with the Vasconic languages. However, lack of data has thus far prevented scholars from determining whether these similarities arose from convergence due to intense contact, or whether Iberian does in fact possess a genetic relationship to the Vasconic languages.
 * Tartessian — Scholarly opinion places Tartessian definitely outside of the Indo-European family, but further classification remains uncertain. Tartessian seems to have borrowed many place names from some Celtic and/or other Indo-European languages; but its syllable structure is totally incompatible with the phonology of any Indo-European language, and much more compatible with the phonology of the Vasconic languages and Iberian. Despite this phonological compatibility, a lack of data has thus far made it impossible to clarify any relationship with the Vasconic languages or Iberian.
 * Indo-European languages
 * Celtic languages
 * Celtiberian
 * Gallaecian
 * (Internally unclassified languages)
 * Lusitanian — Definitely an Indo-European language. Possibly Celtic or Italic, but a lack of data has prevented scholars from determining exactly where Lusitanian fits within the Indo-European family.
 * Sorothaptic (from Greek σορός sorós 'funerary urn' and θαπτός thaptós 'buried') is a hypothetical pre-Celtic language. Joan Coromines identified problematic words in Catalan with inscriptions on lead tablets, from ca. 2nd century CE, found at Amélie-les-Bains on the Catalan–French border. The inscriptions include some Latin but also a non-Latin and non-Celtic component that Coromines identifies with the Urnfield culture from a millennium earlier, claiming to have found such "Sorothaptic" place names across Europe. Like the better-known Vasconic substrate hypothesis, Coromines' Sorothaptic hypothesis has not been well received.

Other Paleohispanic languages can only be identified indirectly through toponyms, anthroponyms or theonyms cited by Roman and Greek sources.

Classification
Of these languages, Celtiberian, Gallaecian, Lusitanian, and presumably Sorothaptic were Indo-European languages; Celtiberian and Gallaecian were Celtic languages, and Lusitanian may also have been, but the hypothetical Sorothaptic was not. Aquitanian was a precursor of Basque, while Tartessian and Iberian remain unclassified.
