' The American Language' Summary

Mencken was inspired by "the argot of the colored waiters" in Washington, as well as one of his favorite authors, Mark Twain, and his experiences on the streets of Baltimore. In 1902, Mencken remarked on the "queer words which go into the making of 'United States.'" The book was preceded by several columns in The Evening Sun. Mencken eventually asked "Why doesn't some painstaking pundit attempt a grammar of the American language... English, that is, as spoken by the great masses of the plain people of this fair land?" 

In the tradition of Noah Webster, who wrote the first American dictionary, Mencken wanted to defend "Americanisms" against a steady stream of English critics, who usually isolated Americanisms as borderline "perversions" of the "mother tongue". Mencken assaulted the prescriptive grammar of these critics and American "schoolmarms", arguing, like Samuel Johnson in the preface to his dictionary, that language evolves independently of textbooks. 

The book discusses the beginnings of "American" variations from "English", the spread of these variations, American names and slang over the course of its 374 pages. According to Mencken, American English was more colourful, vivid, and creative than its British counterpart. 

The book sold exceptionally well by Mencken's standards—1400 copies in the first two months. The book was an early title published by Alfred A. Knopf and was revised three times in the author's lifetime. Reviews of the book praised it lavishly, with the exception of one by Mencken's old nemesis, Stuart Sherman. 

Many of the sources and research material associated with the book are in the Mencken collection at the Enoch Pratt Free Library in Baltimore, Maryland.
