“American Language: A term that presents American English as a national language, sometimes as an aggressive declaration of independence from the standard language of England: ‘This occasional tolerance for things American was never extended to the American language’ (H.L. Mencken, The American Language, 4th edition, 1936); ‘George Bush is hardly known for his rhetorical gifts. But his speech at last summer’s Republican Convention has already left its mark on the American language’ (Laurence Zuckerman, ‘Read My Cliché,’ Time, 16 Jan. 1989).”
