“The true structure of the Welsh grammar will be revealed only when we look at sentences slightly more complicated than its basic VSO pattern. Welsh is no different from the rest of the world: it does involve an extra step, but even that isn't all that unusual. Welsh is like Shakespearean English on acid: the verb always - not just in questions - moves to the beginning. Alternatively, it can be viewed as taking the French grammar a step further. While the verb stops at tense in French, it moves further in Welsh to a position that traditional grammarians call the complementizer (don't ask).”

“So is language change progress or degeneration? It is neither, of course. To assert that language change is for the better or worse requires some measure of what "good" or "bad" language is, and the issue of language change needn't come into question here. But no coherent criterion has ever been given: upon examination, the pronouncements of the self-appointed pundits are always a mix of cultural biases, half-understandings of languages, and an obvious compulsion for telling people what to do.”

“Language is what we use to tell stories, transmit knowledge, and build social bonds. It comforts, tickles, excites, and destroys. Every society has language, and somehow we all learn a language in the first few years of our lives, a process that has been repeated for as long as humans have been around. Unlike swimming, using Microsoft Windows, or making the perfect lemon souffle — which some of us never manage to do — learning a language is a task we can all take for granted.”

“Is language actually getting better, shorter, and easier? Nowadays we often hear exactly the opposite. Teenager slang is awful, students no longer learn Latin, our children — not to mention our president — cannot put together a grammatical sentence. The whimsical poet Ogden Nash was at least half serious in his “Laments for a dying language”:Coin brassy words at will, debase the coinage;We're in an if-you-cannot-lick-them-join age, A slovenliness-provides-its-own-excuse age, Where usage overnight condones misusage. Farewell, farewell to my beloved language,Once English, now a vile orangutanguage.”

“Now we have come full circle to the subtitle of this book: children learn by unlearning other languages. Viewed in the Darwinian light, all humanly possible grammars compete to match the language spoken in the child's environment. And fitness, because we have competition, can be measured by the compatibility of a grammar with what a child hears in a particular linguistic environment. This theory of language takes both nature and nurture into account: nature proposes, and nurture disposes.”

“Universal grammar is about what language is: it is to be distinguished from prescriptive grammars, often distilled in newspaper columns, which tell us what language should be. We are all entitled to our own opinions of what is appropriate, be it in the arrangement of words or flowers - as long as we keep in mind that these are just opinions. The properties of universal grammar linguists have unearthed, however, are a useful defense when language "authorities" try to rationalize their pontifications: none of the don'ts they advertise can be found in the book of universal grammar.”
