English is a West Germanic language that originated from Anglo-Frisian dialects brought to Britain in the mid 5th to 7th centuries AD by Germanic invaders and settlers from what is now northwest Germany, west Denmark and the Netherlands, displacing the Celtic languages that previously predominated.
German ("Deutsch" ] ) is a West Germanic language that is mainly spoken in Central Europe.
 It is the most widely spoken and (co-) official language in Germany, Austria, Switzerland, South Tyrol (Italy), the German-speaking Community of Belgium, and Liechtenstein.
 It is also one of the three official languages of Luxembourg.
 The languages which are most similar to German are the other members of the West Germanic language branch: Afrikaans, Dutch, English, the Frisian languages, Low German/Low Saxon, Luxembourgish, and Yiddish.
 German is the second most widely spoken Germanic language, after English.
Afrikaans ( ) is a West Germanic language spoken in South Africa, Namibia and, to a lesser extent, Botswana and Zimbabwe.
 It evolved from the Dutch vernacular of South Holland (Hollandic dialect) spoken by the mainly Dutch settlers of what is now South Africa, where it gradually began to develop distinguishing characteristics in the course of the 18th century.
 Hence, it is a daughter language of Dutch, and was previously referred to as "Cape Dutch" (a term also used to refer collectively to the early Cape settlers) or "kitchen Dutch" (a derogatory term used to refer to Afrikaans in its earlier days).
 However, it is also variously described as a creole or as a partially creolised language.
 The term is ultimately derived from Dutch "Afrikaans-Hollands " meaning "African Dutch".
 It is the first language of most of the Afrikaners and Coloureds of Southern Africa.
Old Saxon, also known as Old Low German, was a Germanic language and the earliest recorded form of Low German (spoken nowadays in Northern Germany, the northeastern Netherlands, southern Denmark, the Americas and parts of Eastern Europe).
 It is a West Germanic language, closely related to the Anglo-Frisian languages.
 It has been documented from the 8th century until the 12th century, when it gradually evolved into Middle Low German.
 It was spoken throughout modern northwestern Germany, primarily in the coastal regions and in the eastern Netherlands by Saxons, a Germanic tribe who inhabited the region of Saxony.
 It partially shares Anglo-Frisian's (Old Frisian, Old English) Ingvaeonic nasal spirant law which sets it apart from Low Franconian and Irminonic languages, such as Dutch, Luxembourgish and German.
Syldavian is a fictional West Germanic language created by Hergé as the national language of Syldavia, a small fictional Balkan kingdom that serves as a major setting in many of "The Adventures of Tintin" stories.
 Hergé modeled the language on Marols, a dialect of Dutch spoken in and around Brussels.
 The entire corpus of the language has been analyzed by Mark Rosenfelder.
English is a West Germanic language that was first spoken in early medieval England and is now a global "lingua franca".
 Named after the Angles, one of the Germanic tribes that migrated to England, it ultimately derives its name from the Anglia (Angeln) peninsula in the Baltic Sea.
 It is closely related to the Frisian languages, but its vocabulary has been significantly influenced by other Germanic languages, particularly Norse (a North Germanic language), as well as by Latin and Romance languages, particularly French.
Northwest Germanic is a proposed grouping of the Germanic languages, representing the current consensus among Germanic historical linguists.
 It does not challenge the late 19th-century tri-partite division of the Germanic dialects into North Germanic, West Germanic and East Germanic, but proposes additionally that North and West Germanic (i.e. all surviving Germanic languages today) remained as a subgroup after the southward migration of the East Germanic tribes, only splitting into North and West Germanic later.
 Whether this subgroup constituted a unified proto-language, or simply represents a group of dialects that remained in contact and close geographical proximity, is a matter of debate.
 The date by which such a grouping must have dissolved—in that innovations ceased to be shared—is also contentious, though it seems unlikely to have persisted after 500 AD, by which time the Anglo-Saxons had migrated to England and the Elbe Germanic tribes had settled in Southern Germany.
