There is evidence that, at least from the a.d. 2nd century, the vocabulary and phonology of Roman Tarraconensis was different from the rest of Roman Hispania. Differentiation has arisen generally because Spanish, Asturian, and Galician-Portuguese share certain peripheral archaisms (Spanish hervir, Asturian/Portuguese ferver vs. Catalan bullir, Occitan bolir "to boil") and innovatory regionalisms (Sp novillo, Ast nuviellu vs. Cat torell, Oc taurèl "bullock"), while Catalan has a shared history with the Western Romance innovative core, especially Occitan.
