designation "low" to refer to the region has also been in use many times. First by the Romans, who called it Germania "Inferior". After the Frankish empire was divided several times, most of it became the Duchy of Lower Lorraine in the tenth century, where the Low Countries politically have their origin. Lower Lorraine disintegrated into a number of duchies, counties and bishoprics. Some of these became so powerful, that their names were used as a pars pro toto for the Low Countries, i.e., Flanders, Holland and to a lesser extent Brabant. Burgundian, and later Habsburg rulers added one by one the Low Countries' polities in a single territory, and it was at their francophone courts that the term les pays de par deçà arose, that would develop in Les Pays-Bas or in English "Low Countries" or "Netherlands". Theodiscus and derivatives Dutch, Diets and Duyts English is the only language to use the adjective Dutch for the language of the Netherlands and Flanders or something else from the Netherlands. The word is derived from Proto-Germanic . The stem of this word, , meant "people" in Proto-Germanic, and was an adjective-forming suffix, of which is the Modern English form. was its Latinised form and used as an adjective referring to the Germanic vernaculars of the Early Middle Ages. In this sense, it meant "the language of the common people", that is, the native Germanic language. The term was used as opposed to Latin, the non-native language of writing and the Catholic Church. It was first recorded in 786, when the Bishop of Ostia writes to Pope Adrian I about a synod taking place in Corbridge, England, where the decisions are being written down "tam Latine quam theodisce" meaning "in Latin as well as Germanic". So in this sense theodiscus referred to the Germanic language spoken in Great Britain, which was later replaced by the name Englisc. By the late 14th century, þēodisc had given rise to Middle English duche and its variants, which were used as a blanket term for all the non-Scandinavian Germanic languages spoken on the European mainland. Historical linguists have noted that the medieval "Duche" itself most likely shows an external Middle Dutch influence, in that it shows a voiced alveolar stop rather than the expected voiced dental fricative. This would be a logical result of the Medieval English wool trade, which brought the English in close linguistic
