English is a West Germanic language that originated in Anglo-Saxon England. As a result of the military, economic, scientific, political and cultural influence of the British Empire during the 18th, 19th and 20th centuries and of the United States since the late 19th century, it has become the lingua franca in many parts of the world. It is used extensively as a second language and as an official language in Commonwealth countries and many international organizations.

Historically, English originated from several dialects, now called Old English, which were brought to Great Britain by Anglo-Saxon settlers beginning in the 5th century. The language was heavily influenced by the Old Norse language of Viking invaders. After the Norman conquest, Old English developed into Middle English, borrowing heavily from the Norman (Anglo-French) vocabulary and spelling conventions. Modern English developed from there and continues to adopt foreign words from a variety of languages, as well as coining new words. A significant number of English words, especially technical words, have been constructed based on roots from Latin and ancient Greek.

Significance

Modern English, sometimes described as the first global lingua franca, is the dominant international language in communications, science, business, aviation, entertainment, radio and diplomacy. Its spread beyond the British Isles began with the growth of the British Empire, and by the late nineteenth century its reach was truly global. It is the dominant language in the United States, whose growing economic and cultural influence and status as a global superpower since World War II have significantly accelerated the language's adoption across the planet.

A working knowledge of English has become a requirement in a number of fields, occupations and professions such as medicine and computing; as a consequence over a billion people speak English to at least a basic level (see English language learning and teaching). It is also one of six official languages of the United Nations.

Linguists such as David Crystal recognize that one impact of this massive growth of English, in common with other global languages, has been to reduce native linguistic diversity in many parts of the world, most particularly in Australasia and North America, and its huge influence continues to play an important role in language attrition. Similarly, historical linguists, aware of the complex and fluid dynamics of language change, are always aware of the potential English contains through the vast size and spread of the communities that use it and its natural internal variety, such as in its creoles and pidgins, to produce a new family of distinct languages over time.

History

main: History of the English language

English is a West Germanic language that originated from the Anglo-Frisian and Lower Saxon dialects brought to Britain by Germanic settlers and Roman auxiliary troops from various parts of what is now northwest Germany and the northern NetherlandsFact: date=October 2008 in the 5th century. One of these Germanic tribes were the Angles, who may have come from Angeln, and Bede wrote that their whole nation came to Britain, leaving their former land empty. The names 'England' (or 'Aenglaland') and English are derived from the name of this tribe.
The Anglo Saxons began invading around 449 AD from the regions of Denmark and Jutland, Before the Anglo-Saxons arrived in England the native population spoke Brythonic, a Celtic language. Although the most significant changes in dialect occurred after the Norman invasion of 1066, the language retained its name and the pre-Norman invasion dialect is now known as Old English.
