langue d'oïl formerly spoken in the British Isles From Wikipedia, the free encyclopedia
The Anglo-Norman language is the name given to the special sort of the Norman language spoken by the Anglo-Normans, the descendants of the Normans who ruled the Kingdom of England following the conquest by William of Normandy in 1066. This langue d'oïl became the official language of England and later developed into the unique insular dialect now known as the Anglo-Norman language. It was much like Old French.
Anglo-Norman was the spoken language of the Norman nobility and was also used in the courts.
