Anglo-Frisian languages in the context of Sound change

English literature is a form of literature written in the English language from the English-speaking world. The English language has developed over more than 1,400 years. The earliest forms of English, a set of Anglo-Frisian dialects brought to Great Britain by Anglo-Saxon settlers in the fifth century, are called Old English. Beowulf is the most famous work in Old English. Despite being set in Scandinavia, it has achieved national epic status in England. However, following the Norman Conquest of England in 1066, the written form of the Anglo-Saxon language became less common. Under the influence of the new aristocracy, French became the standard language of courts, parliament, and polite society. The English spoken after the Normans came is known as Middle English. This form of English lasted until the 1470s, when the Chancery Standard (late Middle English), a London-based form of English, became widespread. Geoffrey Chaucer, author of The Canterbury Tales, was a significant figure developing the legitimacy of vernacular Middle English at a time when the dominant literary languages in England were still French and Latin. The invention of the printing press by Johannes Gutenberg in 1439 also helped to standardise the language, as did the King James Bible (1611), and the Great Vowel Shift.

Poet and playwright William Shakespeare is widely regarded as the greatest writer in the English language and one of the world's greatest dramatists. His plays have been translated into every primary living language and are performed more often than those of any other playwright. In the nineteenth century, Sir Walter Scott's historical romances inspired a generation of European painters, composers, and writers.

More than 100 complete translations into English languages have been produced.Translations of Biblical books, especially passages read in the Liturgy can be traced back to the late 7th century, including translations into Old and Middle English.

The Frisian languages (/ˈfriːʒən/ FREE-zhən or /ˈfrɪziən/ FRIZ-ee-ən) are a closely related group of West Germanic languages, spoken by about 400,000 Frisian people, who live on the southern fringes of the North Sea in the Netherlands and Germany. The Frisian languages are the closest living language group to the Anglic languages; the two groups make up the Anglo-Frisian languages group and together with the Low German dialects these form the North Sea Germanic languages. Despite the close genetic relationship between English and Frisian, the modern languages are not mutually intelligible. Geographical and historical circumstances have caused the two languages to drift apart linguistically.

Frisian is traditionally divided into three branches often labeled distinct Frisian languages even though the dialects within each branch are not necessarily mutually intelligible. West Frisian is by far the most spoken of the three and is an official language in the Dutch province of Friesland, where it is spoken on the mainland and on two of the West Frisian Islands: Terschelling and Schiermonnikoog. It is also spoken in four villages in the Westerkwartier of the neighbouring province of Groningen. North Frisian, the second branch, is spoken in the northernmost German district of Nordfriesland in the state of Schleswig-Holstein, on the North Frisian mainland and on the North Frisian Islands of Sylt, Föhr, Amrum, and the Halligs. It is also spoken on the islands of Heligoland and Düne in the North Sea. The third Frisian branch, East Frisian, has only one remaining variant, Sater Frisian, spoken in the municipality of Saterland in the Lower Saxon district of Cloppenburg. Surrounded by bogs, the four Saterlandic villages lie just outside the borders of East Frisia, in the Oldenburg Münsterland region. In East Frisia proper, East Frisian Low Saxon is spoken today, which is not a Frisian language, but a variant of Low German/Low Saxon.

The Brittonic languages (also Brythonic or British Celtic; Welsh: ieithoedd Brythonaidd/Prydeinig; Cornish: yethow brythonek/predennek; and Breton: yezhoù predenek) form one of the two branches of the Insular Celtic languages; the other is Goidelic. It comprises the extant languages Breton, Cornish, and Welsh. The name Brythonic was derived by Welsh Celticist John Rhys from the Welsh word Brython, denoting a Celtic Briton as distinguished from Anglo-Saxons or Gaels.

The Brittonic languages derive from the Common Brittonic language, spoken throughout Great Britain during the Iron Age and Roman period. In the 5th and 6th centuries emigrating Britons also took Brittonic speech to the continent, most significantly in Brittany and Britonia. During the next few centuries, in much of Britain the language was replaced by Old English and Scottish Gaelic, with the remaining Common Brittonic language splitting into regional dialects, eventually evolving into Welsh, Cornish, Breton, Cumbric, and probably Pictish. Welsh and Breton continue to be spoken as native languages, while a revival in Cornish has led to an increase in speakers of that language. Cumbric and Pictish are extinct, having been replaced by Goidelic and Anglic speech. There is also a community of Brittonic language speakers in Y Wladfa (the Welsh settlement in Patagonia).

West Frisian (Westerlauwersk Frysk; Dutch: Westerlauwers Fries), or simply Frisian (Frysk [frisk]; Dutch: Fries [fris]), is a West Germanic language spoken mostly in the province of Friesland (Fryslân) in the north of the Netherlands, mostly by those of Frisian ancestry. It is the most widely spoken of the Frisian languages.

In the study of the evolution of English, West Frisian is notable as being the most closely related foreign tongue to the various dialects of Old English spoken across the Heptarchy, these being part of the Anglo-Frisian branch of the West Germanic family.

North Frisian is a minority language of Germany, spoken by about 10,000 people in North Frisia. The language is part of the larger group of the West Germanic Frisian languages. The language comprises 10 dialects which are themselves divided into an insular and a mainland group.

North Frisian is closely related to the Saterland Frisian language of Northwest Germany and West Frisian which is spoken in the Netherlands. All of these are also closely related to the English language forming the Anglo-Frisian group.

Old Frisian was a West Germanic language spoken between the late 13th century and the end of 16th century. It is the common ancestor of all the modern Frisian languages except for the Insular North Frisian dialects, with which Old Frisian shares a common ancestor called Pre–Old Frisian or Proto-Frisian. Old Frisian was spoken by contemporary Frisians who comprised a loose confederacy along the North Sea coast from around modern-day Bruges in Belgium to the Weser in modern-day northern Germany, dominating maritime trade. The vast majority of the surviving literature comprises legal documents and charters, though some poetry, historiographies, and religious documents are attested as well.

Old Frisian was closely related to and shared common characteristics with the forms of English and Low German spoken during the period. Although earlier scholarship contended that Frisian and English had a closer relationship to each other than to Low German, this is no longer the prevailing view. Old Frisian evolved into Middle Frisian around the turn of the 17th century, being largely pushed out by the emergence of Middle Low German as the language of trade in the North Sea. Scholars have argued that the term "Old Frisian" is somewhat misleading, since Old Frisian was contemporary with other Germanic languages during their "Middle" period, such as Middle English and Middle High German.

In historical linguistics, the Ingvaeonic nasal spirant law (also called the Anglo-Frisian or North Sea Germanic nasal spirant law) is a description of a phonological development that occurred in the Ingvaeonic dialects of the West Germanic languages. This includes Old English, Old Frisian, and Old Saxon, and to a lesser degree Old Dutch (Old Low Franconian).
