Pronoun Trouble

"The nature of language is to shift and evolve-but every so often, a new usage creates a whole lot of consternation. These days, pronouns are throwing curve balls, and it matters, because pronoun habits die hard. If you need a refresher from eighth grade English: pronouns are short, used endlessly, and serve to point and direct, to orient us as to what is meant about who. Him, not her. Me, not you.

The singular "they" has been with us since the 1400s and appears in Shakespeare. In fact, many of the supposedly iron-clad rules of grammar are up for debate (Billy and me went to the store is perfectly acceptable!), and with tasty trivia, unexpected twists, and the weird quirks of early and contemporary English, McWhorter guides readers on a journey of how our whole collection of these little words emerged and has changed over time"-- Provided by publisher.
