Rosemarie Ostler is a linguist and former librarian whose writing focuses on language-related topics, especially American English, word histories, and grammar and style. Her most recent book, Founding Grammars, explores the power of grammar rules and the centuries-long debate over how Americans should talk. Previous books showcase the colorful language of America's past, including obsolete twentieth-century slang, the origins of our most common expressions, and the country's long tradition of outrageous political invective. She is currently at work on a book about how English speakers in early America invented their own brand of speech—not just new words, but a picturesque new way of using the language.
Rosemarie's articles cover a broad range of topics, from the fate of endangered languages to plain English for business owners. Her byline has appeared in The Saturday Evening Post, American History, Christian Science Monitor, Whole Earth, Entrepreneur.com, and Elks Magazine, among other places. She has also written about research, usage, and style for Writer's Digest and The Writer, as well as offering workshops on research how-to for writers.
Rosemarie is a member of the American Society of Journalists and Authors. She lives in Eugene, Oregon with her husband, historian Jeff Ostler, and their cat, Calvin. She tweets at @Ostlerwords.
