West Iberian languages

The West Iberian languages are a branch of Romance languages. They were first spoken in central and western parts of Iberia. Spanish and Portuguese are the main languages in the branch. They have been spread to Latin America since the colonial era. There are five branches of West Iberian languages. They are Castilian, Galician-Portuguese, Astur-Leonese, Barranquian, and Pyrenean–Mozarabic. Until recently, all speakers of West Iberian languages could understand each other, but now the branches are too different.
