Among the archaisms retained were allow, guess, and reckon, all used in a sense which had become obsolete in England. Coinages included lightning rod, log cabin, hired hand, and cotton gin. Borrowed words like boss and levee were also Americanisms, as were fork for river branch, spell for time or while, and Thomas Jefferson's 1787 coinage, belittle. A list compiled in 1781 showed mad for angry, to take in and to bamboozle for to swindle, and a heavy use of ain't and other contractions. Common grammatical errors (lay for lie, knowed for knew) and mispronunciations (winder for window) were also included.
