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:
The British and Irish governments recognize Jèrriais and Guernésiais as regional languages within the framework of the British–Irish Council. Sercquiais is in fact a descendant of the 16th-century Jèrriais used by the original colonists from Jersey who settled the then uninhabited island.
The last first-language speakers of Auregnais, the dialect of Norman spoken on Alderney, died during the 20th century, although some rememberers are still alive. The dialect of Herm also lapsed at an unknown date; the patois spoken there was likely Guernésiais (Herm was not inhabited all year round in the Norman culture's heyday).
An isogloss termed the "Joret line" (ligne Joret) separates the northern and southern dialects of the Norman language (the line runs from Granville, Manche to the French-speaking Belgian border in the province of Hainaut and Thiérache). Dialectal differences also distinguish western and eastern dialects.
Three different standardized spellings are used: continental Norman, Jèrriais, and Dgèrnésiais. These represent the different developments and particular literary histories of the varieties of Norman. Norman may therefore be described as a pluricentric language.
The Anglo-Norman dialect of Norman served as a language of administration in England following the Norman conquest of England in 1066. This left a legacy of Law French in the language of English courts (though it was also influenced by Parisian French). In Ireland, Norman remained strongest in the area of south-east Ireland, where the Hiberno-Normans invaded in 1169. Norman remains in (limited) use for some very formal legal purposes in the UK, such as when the monarch gives royal assent to an Act of Parliament using the phrase, "La Reyne (le Roy) le veult" ("The Queen (the King) wills it").
The Norman conquest of southern Italy in the 11th and 12th centuries brought the language to Sicily and the southern part of the Italian Peninsula, where it may have left a few words in the Sicilian language. See: Norman and French influence on Sicilian.
Literature in Norman ranges from early Anglo-Norman literature through the 19th-century Norman literary renaissance to modern writers (see list of Norman-language writers).
As of 2017Duchy of Normandy: the Channel Islands and the Cotentin Peninsula (Cotentinais) in the west, and the Pays de Caux (Cauchois dialect) in the east. Ease of access from Paris and the popularity of the coastal resorts of central Normandy, such as Deauville, in the 19th century led to a significant loss of distinctive Norman culture in the central low-lying areas of Normandy.
the Norman language remains strongest in the less accessible areas of the former
