In this week’s Spectator Books podcast Sam's guest is Benjamin Dreyer — whose name is pronounced, as Sam discovers live on air, 'Dryer' rather than 'Drayer'. That seems an apt way to be introduced to a man who, as Random House US’s Copy Chief, makes his living correcting errors. His new book Dreyer’s English is a compendium of useful tricks of the trade, sharp opinions and authoritative rulings on everything to do with language and style. They talk transatlantic language differences, angry pedants, and punctuation nitty-gritty, with special reference to Steven Pinker, the New Yorker and Guns N’ Roses.

Spectator Books is a series of literary interviews and discussions on the latest releases in the world of publishing, from poetry through to physics. Presented by Sam Leith, The Spectator's Literary Editor. Hear past episodes of Spectator Books here.
