English is a branch of West Germanic language, which was first used by Britain in the Middle Ages and became the most widely used language in the world because of its huge colony. The Anglo tribe, the ancestor of the British, is one of the Germanic tribes that later moved to the island of Great Britain and were called England. Both names come from Angeria in the Baltic Peninsula.
This language is closely related to Frisian and Lower Saxon, and its vocabulary is influenced by other Germanic languages, especially Nordic (North Germanic), which is mainly written in Latin and French.
