What is "galician-portuguese"

Galician-Portuguese , also known as Old Portuguese or Medieval Galician, was a West Iberian Romance language spoken in the Middle Ages, in the northwest area of the Iberian Peninsula. Alternatively, it can be considered a historical period of the Galician and Portuguese languages.

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.

It is the common ancestor of modern Portuguese, Galician, Eonavian and Fala varieties. The term "Galician-Portuguese" also designates the subdivision of the modern West Iberian group of Romance languages.
