WikiEnglish is a West Germanic language that arose in the Anglo-Saxon kingdoms of England and spread into what was to become south-east Scotland under the influence of the Anglian medieval kingdom of Northumbria. Following the economic, political, military, scientific, cultural, and colonial influence of Great Britain and the United Kingdom from the 18th century, via the British Empire, and of the United States since the mid-20th century,[5][6][7][8] it has been widely dispersed around the world, become the leading language of international discourse, and has acquired use as lingua franca in many regions.[9][10] It is widely learned as a second language and used as an official language of the European Union and many Commonwealth countries, as well as in many world organizations. It is the third most natively spoken language in the world, after Mandarin Chinese and Spanish.[11]
