English language
Introduction
There are many dialect areas; in England and S Scotland these are of long standing, and the variations are striking; the Scottish dialect especially has been cultivated literarily. There are newer dialect differences also, such as in the United States, including regional varieties such as Southern English, and cultural varieties, such as Black English. Standard forms of English differ also; thus, the standard British (“the king's English”) is dissimilar to the several standard varieties of American and to Australian, Canadian, New Zealand, and Indian English.

A Changed and Changing Language
Like other languages, English has changed greatly, albeit imperceptibly, so that an English speaker of 1300 would not have understood the English of 500 nor the English of today. Changes of every sort have taken place concomitantly in the sounds (phonetics), in their distribution (phonemics), and in the grammar (morphology and syntax). 
Although the pronunciation of English has changed greatly since the 15th cent., the spelling of English words has altered very little over the same period. As a result, English spelling is not a reliable guide to the pronunciation of the language.
The vocabulary of English has naturally expanded, but many common modern words are derived from the lexicon of the earliest English; e.g., 
During these 300 or more years English remained the language of the common people, but an increasingly large number of French words found their way into the language, so that when the 14th-century vernacular revival, dominated by Chaucer and Wyclif, restored English to its old place as the speech of all classes, the French element in the English vocabulary was very considerable. To this phase of French influence belong most legal terms (such as 
The direct influence of the classical languages began with the Renaissance and has continued ever since; even today Latin and Greek roots are the chief source for English words in science and technology (e.g., 
History of English
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 (see Anglo-Saxon literature). 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.
