The West Iberian languages are a branch of the Iberian Romance languages, primarily spoken in the western part of the Iberian Peninsula. This group includes languages such as Portuguese and Galician, which are closely related, as well as Spanish (specifically the Asturleonese and Extremaduran varieties). These languages evolved from Latin, influenced by local languages and cultures. These languages share many grammatical and lexical features, making them mutually intelligible to some extent. The West Iberian languages are significant for their rich literary traditions and cultural heritage, reflecting the history and identity of the regions where they are spoken.
