Classificació i utilitat del substrat preromà de la llengua catalana

Coromines was the principal investigator of the pre-roman substrate of Catalan. This article shows that his main conclusion, namely that the peninsular northeast had a non-Celtic Indoeuropean language, is refuted after reviewing that the supposedly pre-roman lexicon was acquired by Catalan through its narrow relation with the Gallo-Roman group. Once such lexicon is dated, we can look at the true pre-roman lexicon that survived in Catalan as its origin: it was a non-Indoeuropean language (probably the Iberian language), a language with clear links with the actual Basque language, a result that is reinforced by recent discoveries regarding mutual relations between the two languages.
