O português popular europeu dos séculos XVI–XIX e a sua importância para o estudo do Galego Médio

This article is centred around the linguistic information supplied by 16th and 18th century Portuguese grammar books, when, using as a basis the Lisbon variety, these works condemn the use of dialect or popular expressions habitually used. Like Galician, the language spoken in the territories lying to the North of the River Miño did not possess grammatical works until the 19th century, and so the information contained in these Portuguese grammars allows us to approach, with a reasonable degree of reliability, certain features of Middle Galician, a period in which the language, in Galicia, was only used at an oral level and was practically non-existent in any educated or written usage.
