H. L. Mencken,
The American Language — The Materials of the Inquiry
(1919)
“ An Americanism may be defined as a word or phrase, old or new, employed by general or respectable usage in America in a way not sanctioned by the best standards of the English language. As a matter of fact, however, the term has come to possess a wider meaning, and it is now applied not only to words and phrases which can be so described, but also to the new and legitimately born words adapted to the general needs and usages, to the survivals of an older form of English than that now current in the mother country, and to the racy, pungent vernacular of Western life. ”
