Grimm's lawGrimm's law (also known as the First Germanic Sound Shift) is a set of sound laws describing the Proto-Indo-European (PIE) stop consonants as they developed in Proto-Germanic in the 1st millennium BC. First discovered by Rasmus Rask but systematically put forward by Jacob Grimm, it establishes a set of regular correspondences between early Germanic stops and fricatives and stop consonants of certain other centum Indo-European languages. Grimm's law was the first discovered systematic sound change, creating historical phonology as a separate historical linguistics discipline.
Proto-Germanic languageProto-Germanic (abbreviated PGmc; also called Common Germanic) is the reconstructed proto-language of the Germanic branch of the Indo-European languages. Proto-Germanic eventually developed from pre-Proto-Germanic into three Germanic branches during the fifth century BC to fifth century AD: West Germanic, East Germanic and North Germanic, which however remained in contact over a considerable time, especially the Ingvaeonic languages (including English), which arose from West Germanic dialects and remained in continued contact with North Germanic.
HesseHesse (Hessen ˈhɛsn̩), officially the State of Hesse (Land Hessen), is a state in Germany. Its capital city is Wiesbaden, and the largest urban area is Frankfurt, which is also the country's principal financial centre. Two other major historic cities are Darmstadt and Kassel. With an area of 21,114.73 square kilometers and a population of over six million, it ranks seventh and fifth, respectively, among the sixteen German states. Frankfurt Rhine-Main, Germany's second-largest metropolitan area (after Rhine-Ruhr), is mainly located in Hesse.
West Germanic languagesThe West Germanic languages constitute the largest of the three branches of the Germanic family of languages (the others being the North Germanic and the extinct East Germanic languages). The West Germanic branch is classically subdivided into three branches: Ingvaeonic, which includes English and Frisian, Istvaeonic, which encompasses Dutch and its close relatives, and Irminonic, which includes German and its close relatives and variants. English is by far the most-spoken West Germanic language, with more than 1 billion speakers worldwide.
Germanic peoplesThe Germanic peoples were historical groups of people that once occupied Northwestern and Central Europe and Scandinavia during antiquity and into the early Middle Ages. Since the 19th century, they have traditionally been defined by the use of ancient and early medieval Germanic languages and are thus equated at least approximately with Germanic-speaking peoples, although different academic disciplines have their own definitions of what makes someone or something "Germanic".
ElbeThe Elbe (ˈɛlbə; Labe ˈlabɛ; Ilv or Elv; Upper and Łobjo) is one of the major rivers of Central Europe. It rises in the Giant Mountains of the northern Czech Republic before traversing much of Bohemia (western half of the Czech Republic), then Germany and flowing into the North Sea at Cuxhaven, northwest of Hamburg. Its total length is . The Elbe's major tributaries include the rivers Vltava, Saale, Havel, Mulde, Schwarze Elster, and Ohře. The Elbe river basin, comprising the Elbe and its tributaries, has a catchment area of , the twelfth largest in Europe.
ThuringiaThuringia (θəˈrɪndʒiə; Thüringen ˈtyːʁɪŋən), officially the Free State of Thuringia (Freistaat Thüringen ˈfʁaɪʃtaːt ˈtyːʁɪŋən), is a state of central Germany, covering , the sixth smallest of the sixteen German states. It has a population of about 2.1 million. Erfurt is the capital and largest city. Other cities are Jena, Gera and Weimar. Thuringia is bordered by Bavaria, Hesse, Lower Saxony, Saxony-Anhalt, and Saxony. It has been known as "the green heart of Germany" (das grüne Herz Deutschlands) from the late 19th century due to its broad, dense forest.
CeltsThe Celts (kɛlts, see pronunciation for different usages) or Celtic peoples (ˈkɛltɪk) were a collection of Indo-European peoples in Europe and Anatolia, identified by their use of Celtic languages and other cultural similarities. Major Celtic groups included the Gauls; the Celtiberians and Gallaeci of Iberia; the Britons and Gaels of Britain and Ireland; the Boii; and the Galatians. The relation between ethnicity, language and culture in the Celtic world is unclear and debated; for example over the ways in which the Iron Age people of Britain and Ireland should be called Celts.
