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.

Forms of speech now obsolete or provincial in England, which survive in the United States, such as allow, bureau, fall, gotten, guess, likely, professor, shoat. Words and phrases of distinctly American origin, such as belittle, lengthy, lightning-rod, to darken one’s doors, to bark up the wrong tree, to come out at the little end of the horn, blind tiger, cold snap, gay Quaker, gone coon, long sauce, pay dirt, small potatoes, some pumpkins.

Words and phrases stated by the previous compiler himself to be of foreign [i.e., chiefly of English] origin, like Farmer’s hand-me-downs. Names of things exclusively American, but known abroad under the same name, such as moccasin. Names of things invented in the United States, like drawing-room car. Words used in this country in a sense hardly distinguishable from that they bear in England, like force for a gang of laborers. Nonce words, like Mark Twain’s cavalieress. Perfectly regular and self-explanatory compounds, like office-holder, planing-machine, ink-slinger and fly-time.
