English language, member of the West Germanic group of the Germanic subfamily of the Indo-European family of languages.
Spoken by about 470 million people throughout the world, English is the official language of about 45 nations. It is the mother tongue of about 60 million persons in the British Isles, from where it spread to many other parts of the world owing to British exploring, colonizing, and empire-building from the 17th through 19th cent.
Geographic distribution:
As a result of such expansion, English is the most widely scattered of the great speech communities. It is also the most commonly used auxiliary language in the world. The United Nations uses English not only as one of its official languages but also as one of its two working languages.
There are many dialect areas:
History:
Today’s English is the continuation of the language of the 5th-century Germanic invaders of Britain. No records exist of preinvasion forms of the language. The language most closely related to English is the West Germanic language Frisian. The history of English is an aspect of the history of the English people and their development. Thus in the 9th cent. the standard English was the dialect of dominant Wessex. The Norman Conquest (11th cent.) brought in foreign rulers, whose native language was Norman French; and English was eclipsed by French as the official language. When English became again (14th cent.) the language of the upper class, the capital was London, and the new standard (continued in Modern Standard English) was a London dialect.
It is convenient to divide English into periods-Old English (or Anglo-Saxon; to c.1150), Middle English (to c.1500; see Middle English literature), and Modern English; this division implies no discontinuity, for even the hegemony of French affected only a small percentage of the population. The English-speaking areas have expanded at all periods. Before the Normans the language was spoken in England and S Scotland, but not in Cornwall, Wales, or, at first, in Strathclyde. English has not completely ousted the Celtic languages from the British Isles, but it has spread vastly overseas.
