Galician–Portuguese (Galician: galego-portugués or galaico-portugués; Portuguese: galego-português or galaico-português), also known as Old Galician–Portuguese, Galaic-Portuguese, or (in contexts focused on one of the modern languages) Old Galician, Old Portuguese, Medieval Galician or Medieval Portuguese, was a West Iberian Romance language spoken in the Middle Ages, in the northwest area of the Iberian Peninsula. It is both the ancestor language and historical period of development of modern Galician, Fala, Portuguese and Eonavian languages which maintain a high degree of mutual intelligibility.
Galician–Portuguese was first spoken in the area bounded in the north and west by the Atlantic Ocean and by the Douro River in the south, comprising Galicia and northern Portugal, but it was later extended south of the Douro by the Reconquista.
