John McWhorter's book is erudite, totally chock with amazing details about dialects. Everyone should read it and find something to smile about or memories about learning new languages. He parallels the evolution of languages with the evolution of species. When you've read this you'll never think of human tongues in the same way again, or ever believe that one tongue is more sophisticated and worthy than another. Some clichés are also swept aside, like the one that declares that Inuits have 200 words to describe "snow". It feels as if McWhorter has learned a little of every language in the world, and loves to pass on his knowledge, from sheer enjoyment.
