the subject, filling a gap by articulating the unique features that define American English. At the start of the work, Mencken delves into his motivation for writing, noting the inadequacy of existing literature regarding the differences between American and British English. He references historical figures such as Thomas Jefferson and Noah Webster, who anticipated the evolution of a distinctly American dialect, emphasizing the influence of American culture, environment, and innovation. Mencken outlines the neglect of American vernacular by scholars and the need for a deeper understanding and acceptance of American English as a legitimate and evolving language distinct from its British roots. The opening sets the stage for a thorough exploration of topics such as pronunciation, slang, and the impact of immigration on the language. (This is an automatically generated summary.)
