Jonathan Swift had a lifelong interest in the English language. The extent of this interest is extraordinary. It includes language history and theories; dialect, jargon, and slang; vocabulary, orthography, and punctuation; etymology; rhetoric and dialectic; code and private languages; puns and language games; the social and political function of language and its abuse in propaganda. A received view in the extensive modern scholarship on Swift and the English language is that Swift is a linguistic conservative. He deplores the impurity, instability, and impermanence of English and aspires to arrest its obsolescence and purge it of corrupt words. He prescribes standardization in spelling and punctuation. He insists on simplicity and stylistic propriety, which he polices in his satiric invective against offending authors. Yet, paradoxically, Swift's stylistic practice is characterized by unconstrained linguistic freedom. Swift was certainly called to account by contemporary critics for his impropriety. In the “Apology” for his brilliant early satire A Tale of a Tub the “Author” acknowledges that “he gave a Liberty to his Pen, which might not suit with maturer Years, or graver Characters” (PW i: 1-2).
