With wit and irreverence, lexicographer Kory Stamper cracks open the obsessive world of dictionary writing, from the agonizing decisions about what to define and how to do it to the knotty questions of ever-changing word usage. Filled with fun facts—for example, the first documented usage of “OMG” was in a letter to Winston Churchill—and Stamper’s own stories from the linguistic front lines (including how she became America’s foremost “irregardless” apologist, despite loathing the word), is an endlessly entertaining look at the wonderful complexities and eccentricities of the English language.
