Arras as some of the more prominent cities. It was said that the Picard language began at the east door of Notre-Dame de Paris, so far-reaching was its influence. It would also spread northwards in the area of Boulogne-sur-Mer that had a strong presence of Old Dutch and Middle Dutch; Old Norman, in Normandy, whose principal cities were Caen and Rouen. The Norman conquest of England brought many Norman-speaking aristocrats into the British Isles. Most of the older Norman (sometimes called "French") words in English reflects its influence, which became a conduit for the introduction into the Anglo-Norman realm, as did Anglo-Norman control of Anjou and Gascony and other continental possessions. Anglo-Norman was a language that reflected a shared culture on both sides of the English Channel. Ultimately, the language declined and fell, becoming Law French, a jargon spoken by lawyers that was used in English law until the reign of Charles II of England; however, the Norman language, still survives in Normandy and the Channel Islands, as a regional language; Wallon, around Namur, now in Wallonia, Belgium; Gallo of the Duchy of Brittany; Lorrain of the Duchy of Lorraine. Some modern languages are derived from Old French dialects other than Classical French, which is based on the Île-de-France dialect. They include Angevin, Berrichon, Bourguignon-Morvandiau, Champenois, Franc-Comtois, Gallo, Lorrain, Norman, Picard, Poitevin, Saintongeais and Walloon. History Evolution and separation from Vulgar Latin Beginning with Plautus' time (254–184 ), one can see phonological changes between Classical Latin and what is called Vulgar Latin, the common spoken language of the Western Roman Empire. Vulgar Latin differed from Classical Latin in phonology and morphology as well as exhibiting lexical differences; however, they were mutually intelligible until the 7th century when Classical Latin 'died' as a daily spoken language, and had to be learned as a second language (though it was long thought of as the formal version of the spoken language). Vulgar Latin was the ancestor of the Romance languages, including Old French. By the late 8th century, when the Carolingian Renaissance began, native speakers of Romance idioms continued to use Romance orthoepy rules while speaking and reading Latin. When the most prominent scholar of Western Europe at the time, English deacon Alcuin, was tasked by Charlemagne with improving the standards of Latin writing in France, not being a native Romance speaker himself, he prescribed a pronunciation based on a fairly literal interpretation
