when did french stop being the official language of england
Anglo-Norman language When William the Conqueror led the Norman conquest of England in 1066, he, his nobles, and many of his followers from Normandy, but also those from northern and western France, spoke a range of langues d'oïl (northern varieties of Gallo-Romance). One of these was Old Norman, also known as "Old Northern French". Other followers spoke varieties of the Picard language or western French. This amalgam developed into the unique insular dialect now known as Anglo-Norman French, which was commonly used for literary and eventually administrative purposes from the 12th until the 15th century. It is difficult to know much about what was actually spoken, as what is known about the dialect is restricted to what was written, but it is clear that Anglo-Norman was, to a large extent, the spoken language of the higher social strata in medieval England.
