I know a lot of words. Really, I do. I write; I read; words are sort of my thing. My favorite game is Quiddler. There is nothing I love more than Jeopardy's "Crossword Clues Q" (or J or X or...) category. Sometimes I pick up Macbeth and start re-reading it, just for fun.
And yet, the number of words I don't know still seems as large and limitless as it did when I was three years old, and the only word I recognized when my mother would read The Monster at the End of This Book: Starring Lovable, Furry Old Grover to me, was "strength."
For instance, I have just finished reading Atmospheric Disturbances by Rivka Galchen. This was an absolutely (as they say) whip-smart book, featuring a man who believes his wife has been replaced with a simulacrum, a cosmic conflict between the Royal Academy of Meteorology and the 49 Quantum Fathers, a quixotic quest, and a flawlessly executed unreliable first-person narration. Now up there with I, Lucifer, this novel has made it onto the short list of my favorite books. (Incidentally, I came across it, as I do so many of the best books, by randomly browsing the shelves of my local library.)
The point I am slowly meandering toward is that this novel—aside from provoking me into envying Rivka Galcehn's intelligence, command of language, and ability to produce an engaging plot—taught me a lot of new words (see below). And when I think back upon the countless number of books I have read over the course of my life, it frightens me to imagine how much less knowledgeable I would now be without having done so. What I'm saying is this: Please read.
