The American Language by H L Mencken

American author, scholar, and satirist H.L. Mencken wrote The American Language in 1919, intending to defend American speech from prescriptivist critics. “America itself is unutterably vulgar. But vulgarity, after all, means no more than a yielding to natural impulses in the face of conventional inhibitions, and that yielding to natural impulses is at the heart of all healthy language-making.”
