English in America: A Linguistic History
The Rise of American Language Standards
S1 E4:
In the 1800s, America began looking inward, not to England, for its language standards. The new norms were recorded in dictionaries, spelling books, and grammars, and celebrated in a profusion of distinctly American literary works. Noah Webster, Ralph Waldo Emerson, Walt Whitman, and Mark Twain are all key figures in this stage in the historical development of American English.
