The Germanic languages are a branch of the Indo-European language family spoken natively by a population of about 515 million people[nb 1] mainly in Europe, North America, Oceania and Southern Africa. The most widely spoken Germanic language, English, is the world's most widely spoken language with an estimated 2 billion speakers. All Germanic languages are derived from Proto-Germanic, spoken in Iron Age Scandinavia.
The West Germanic languages include the three most widely spoken Germanic languages: English with around 360–400 million native speakers;[3][nb 2] German, with over 100 million native speakers;[4] and Dutch, with 24 million native speakers. Other West Germanic languages include Afrikaans, an offshoot of Dutch, with over 7.1 million native speakers;[5] Low German, considered a separate collection of unstandardized dialects, with roughly 0.3 million native speakers and probably 6.7–10 million people who can understand it[6][7] (at least 5 million in Germany[6] and 1.7 million in the Netherlands);[8] Yiddish, once used by approximately 13 million Jews in pre-World War II Europe,[9] and Scots, both with 1.5 million native speakers; Limburgish varieties with roughly 1.3 million speakers along the Dutch–Belgian–German border; and the Frisian languages with over 0.5 million native speakers in the Netherlands and Germany.
The largest North Germanic languages are Danish, Norwegian and Swedish, which are mutually intelligible and have a combined total of about 20 million native speakers in the Nordic countries and an additional five million second language speakers; since the middle ages these languages have however been strongly influenced by the West Germanic language Middle Low German, and Low German words account for about 30–60% of their vocabularies according to various estimates. Other North Germanic languages are Faroese and Icelandic, which are more conservative languages with no significant Low German influence, more complex grammar and limited mutual intelligibility with the others today.[10]
The East Germanic branch included Gothic, Burgundian, and Vandalic, all of which are now extinct. The last to die off was Crimean Gothic, spoken until the late 18th century in some isolated areas of Crimea.[11]
The SIL Ethnologue lists 48 different living Germanic languages, 41 of which belong to the Western branch and six to the Northern branch; it places Riograndenser Hunsrückisch German in neither of the categories, but it is often considered a German dialect by linguists.[12] The total number of Germanic languages throughout history is unknown as some of them, especially the East Germanic languages, disappeared during or after the Migration Period. Some of the West Germanic languages also did not survive past the Migration Period, including Lombardic. As a result of World War II, the German language suffered a significant loss of Sprachraum, as well as moribundness and extinction of several of its dialects. In the 21st century, its dialects are dying out anyway[nb 3] due to Standard German gaining primacy.[13]
The common ancestor of all of the languages in this branch is called Proto-Germanic, also known as Common Germanic, which was spoken in about the middle of the 1st millennium BC in Iron Age Scandinavia. Proto-Germanic, along with all of its descendants, is characterised by a number of unique linguistic features, most famously the consonant change known as Grimm's law. Early varieties of Germanic entered history with the Germanic tribes moving south from Scandinavia in the 2nd century BC, to settle in the area of today's northern Germany and southern Denmark.
