There are no Western Romance Languages.
Western Romance languages . They include the Gallo-Romance and Iberian-Romance branches as well as northern Italian . The subdivision is based solely on the use of the `` s '' for pluralization and the weakening of some consonants , but that makes the categorization highly problematic because there is much higher lexical similarity between all dialects of Italian and French than between French and Spanish . Based on mutual intelligibility , Dalby counts a dozen languages : Portuguese , Spanish , Asturian-Leonese , Aragonese , Catalan , Gascon , Provençal , Gallo-Wallon , French , Franco-Provençal , Romansh , and Ladin .
