So many of us walk around letting fly with “errors.” We could do better, but we’re so slovenly, so rushed amid the hurly-burly of modern life, so imprinted by the “let it all hang out” ethos of the sixties, that we don’t bother to observe the “rules” of “correct” grammar.
To a linguist, if I may share, these “rules” occupy the exact same place as the notion of astrology, alchemy, and medicine being based on the four humors. The “rules” make no logical sense in terms of the history of our language, or what languages around the world are like.
Nota bene: linguists savor articulateness in speech and fine composition in writing as much as anyone else. Our position is not—I repeat, not—that we should chuck standards of graceful composition. All of us are agreed that there is usefulness in a standard variety of a language, whose artful and effective usage requires tutelage. No argument there.
The argument is about what constitutes artful and effective usage. Quite a few notions that get around out there have nothing to do with grace or clarity, and are just based on misconceptions about how languages work.
