Document 2: Old English: Old English is a West Germanic language, developing out of Ingvaeonic (also known as North Sea Germanic) dialects from the 5th century. It came to be spoken over most of the territory of the Anglo-Saxon kingdoms which became the Kingdom of England. This included most of present-day England, as well as part of what is now southeastern Scotland, which for several centuries belonged to the Anglo-Saxon kingdom of Northumbria. Other parts of the island – Wales and most of Scotland – continued to use Celtic languages, except in the areas of Scandinavian settlements where Old Norse was spoken. Celtic speech also remained established in certain parts of England: Medieval Cornish was spoken all over Cornwall and in adjacent parts of Devon, while Cumbric survived perhaps to the 12th century in parts of Cumbria, and Welsh may have been spoken on the English side of the Anglo-Welsh border. Norse was also widely spoken in the parts of England which fell under Danish law.
Document 3: Languages of Sweden: Swedish evolved from Old Norse around the 14th and 15th century, and historically, the Swedish dialects were generally much more different than today. Since the 20th century Standard Swedish prevails throughout the country. The Scandinavian languages constitute a dialectal continuum and some of the traditional Swedish dialects could equally be described as Danish (Scanian) or Norwegian (Jamtlandic).

Document 7: Old English: Old English developed from a set of Anglo-Frisian or North Sea Germanic dialects originally spoken by Germanic tribes traditionally known as the Angles, Saxons, and Jutes. As the Anglo-Saxons became dominant in England, their language replaced the languages of Roman Britain: Common Brittonic, a Celtic language, and Latin, brought to Britain by Roman invasion. Old English had four main dialects, associated with particular Anglo-Saxon kingdoms: Mercian, Northumbrian, Kentish and West Saxon. It was West Saxon that formed the basis for the literary standard of the later Old English period, although the dominant forms of Middle and Modern English would develop mainly from Mercian. The speech of eastern and northern parts of England was subject to strong Old Norse influence due to Scandinavian rule and settlement beginning in the 9th century.

Document 12: Dutch language: Old Dutch naturally evolved into Middle Dutch. The year 1150 is often cited as the time of the discontinuity, but it actually marks a time of profuse Dutch writing and during this period a rich Medieval Dutch literature developed. There was at that time no overarching standard language; Middle Dutch is rather a collective name for a number of closely related dialects whose ancestor was Old Dutch. But they were all mutually intelligible. In fact, since Dutch is a rather conservative language, the various literary works of that time today are often very readable for modern-day speakers.
Document 13: Johan Bernhard Hjort: Johan Bernhard Hjort (25 February 1895 – 24 February 1969) was a Norwegian supreme court lawyer. Having joined the law firm of Harald Nørregaard in 1932, he continued the firm after World War II as Advokatfirmaet Hjort, which today is one of Norway's leading law firms. Hjort was also noted for his involvement with the fascist party, Nasjonal Samling, in the 1930s, but left the party in 1937 and became an active member of the anti-Nazi resistance during World War II. He was imprisoned by the Nazis and is credited with saving the lives of many prisoners through his involvement with the White Buses. After World War II, he rose to become one of Norway's preeminent lawyers, and was noted for his defence of gay rights and controversial artists, as chairman of the Riksmålsforbundet language society, and as a liberal public figure.

Document 15: Switzerland: Aside from the official forms of their respective languages, the four linguistic regions of Switzerland also have their local dialectal forms. The role played by dialects in each linguistic region varies dramatically: in the German-speaking regions, Swiss German dialects have become ever more prevalent since the second half of the 20th century, especially in the media, such as radio and television, and are used as an everyday language, while the Swiss variety of Standard German is almost always used instead of dialect for written communication (c.f. diglossic usage of a language). Conversely, in the French-speaking regions the local dialects have almost disappeared (only 6.3% of the population of Valais, 3.9% of Fribourg, and 3.1% of Jura still spoke dialects at the end of the 20th century), while in the Italian-speaking regions dialects are mostly limited to family settings and casual conversation.
