English (English: English) is a West Germanic branch of the language first used in medieval England and, because of its vast colonies, the most widely spoken language in the world. The ancestral Anglo tribes of the English were among the Germanic tribes that later migrated to the region of the island of Great Britain known as England. Both names are derived from Anglia in the Baltic Peninsula.The language is closely related to Frisian and Lower Saxon, and its vocabulary has been influenced by other Germanic languages, notably Scandinavian (North Germanic), and is largely written in Latin and French.
