Patricia T. O’Conner in the New York Times Book Review:
Get a few language types together, and before long someone will bring up the great divide between the preservers and the observers of English, the “prescriptivists” and the “descriptivists” — those who’d rap your knuckles for using “snuck” versus those who might cite Anglo-Saxon cognates in its defense.
The truth is that the divide isn’t nearly as great as it’s made out to be. Most grammarians, lexicographers, usage experts and linguists are somewhere in between: English is always changing, but that doesn’t mean anything goes.
Ben Yagoda, the author of “When You Catch an Adjective, Kill It,” is with the right-thinking folks in the middle. His book, an ode to the parts of speech, isn’t about the rights or wrongs of English. It’s about the wonder of it all: the beauty, the joy, the fun of a language enriched by poets like Lily Tomlin, Fats Waller and Dizzy Dean (to whom we owe “slud,” as in “Rizzuto slud into second”).
