Anglo-Norman (Norman: Anglo-Normaund; French: Anglo-normand), also known as Anglo-Norman French, was a dialect of Old Norman that was used in England and, to a lesser extent, other places in Great Britain and Ireland during the Anglo-Norman period. According to some linguists, the name Insular French might be more suitable, because "Anglo-Norman" is constantly associated with the notion of a mixed language based on English and Norman. According to some, such a mixed language never existed. Other sources, however, indicate that such a language did exist, and that it was the language descended from the Norman French originally established in England after the Conquest.
