Norman or Norman French (Normaund, Normand nɔʁmɑ̃, Guernésiais: Normand, Jèrriais: Nouormand) is a Romance language which can be classified as one of the langues d'oïl, which also includes French, Picard and Walloon. The name "Norman French" is sometimes used to describe not only the Norman language, but also the administrative languages of Anglo-Norman and Law French used in England. For the most part, the written forms of Norman and modern French are mutually intelligible. This intelligibility was largely caused by the Norman language's planned adaptation to French orthography (writing).
When Norse Vikings from modern day Scandinavia arrived in Neustria, in the western part of the then Kingdom of the Franks, and settled the land that became known as Normandy, these North-Germanic–speaking people came to live among a local Gallo-Romance–speaking population. In time, the communities converged, so that Normandy continued to form the name of the region while the original Norsemen were largely assimilated by the Gallo-Romance people, adopting their speech but still contributing some elements from Old Norse language and Norse culture. Later, when conquering England, the Norman rulers in England would eventually assimilate, thereby adopting the speech of the local English. In both cases, the elites contributed elements of their own language to the newly enriched languages that developed in the territories.
In Normandy, the Norman language inherited only some 150 words from Old Norse. The influence on phonology is disputed, although it is argued that the retention of aspirated h and k in Norman is due to Norse influence.
Norman is spoken in mainland Normandy in France, where it has no official status, but is classed as a regional language. It is taught in a few colleges near Cherbourg-Octeville.
In the Channel Islands, the Norman language has developed separately, but not in isolation, to form:
Jèrriais (in Jersey)
Guernésiais or Dgèrnésiais or Guernsey French (in Guernsey)
Sercquiais (or Sarkese, in Sark)
Auregnais (in Alderney)
The British and Irish governments recognize Jèrriais and Guernésiais as regional languages within the framework of the British–Irish Council.
