American English developed as a distinct variety from British English starting in the 17th century with the English colonization of North America. Some expressions considered "Americanisms" today were originally British terms that were preserved in America but later lost in Britain. Spanish also influenced American English with words like canyon, ranch, and stampede. American English went through periods of divergence from British English during the Colonial period, establishment as a standard during the National period, and international influence during the modern International period as American culture has spread globally.
2. From around 1600, the English colonization of North America resulted in the creation of a
distinct American variety of English.
In some ways, American English is more like the English of Shakespeare than modern British
English is.
Some expressions that the British call "Americanisms" are in fact original British expressions that
were preserved in the colonies while lost for a time in Britain (for example trash for
rubbish, loan as a verb instead of lend, and fall for autumn; another example, frame-up, was
re-imported into Britain through Hollywood gangster movies).
3. Spanish also had an influence on American English (and subsequently British
English),with words:
canyon
ranch,
stampede
vigilante
4. The Periods of American English
The Colonial Period (1607-1776), birth of distinctive American English;
The National Period (1776-1898) establishment and consolidation of
American English;
The International Period (from 1898) AE has influenced other varieties of
English and other languages.
5. The Colonical Period
Divergent features leveled inside a single colony.
The barrier of the Atlantic began the process of divergence of American from British usage
almost immediately.
6. The National Period
Linguistically, this period faced two related challenges:
the evolution and recognition of a separate standard English for the USA;
the extension of that standard over the whole nation as it expanded westward (Noah
Webster Federal English)
7. The International Period
The USA played an increasing role in world politics and economics with a consequent effect
on AE usage.
Spread of AE and American pop culture throughout the world.
9. Today, American English is particularly influential, due to the USA's dominance of cinema,
television, popular music, trade and technology (including the Internet).
But there are many other varieties of English around the world, including for example Australian
English, New Zealand English, Canadian English, South African English, Indian English and
Caribbean English.
