West Iberian is a branch of the
Romance languages that includes Pyrenean–Mozarabic (
Aragonese),
Castilian (
Spanish and
Judaeo-Spanish/Ladino),
Astur-Leonese (
Asturian,
Extremaduran,
Leonese,
Mirandese and
Cantabrian), and the modern descendants of
Galician-Portuguese (
Galician,
Portuguese, and the
Fala language). According to
historical linguistic analysis, these languages are significantly closer to each other in historical terms than to any other living language in the peninsula—including
Catalan, the other major Romance language of the
Iberian Peninsula.
