  • Well, they ought to have just renamed the river then, don't you think?

  • I wrote a rather embarassing paper in college where I confused the generic term "riparian" with the name of a local river, the Rapidan.

  • I just heard the word "riparian" for the first time ever today used twice in an NPR story on the California levees and wondered what the heck it meant. Now I know.

    I love coming across new words, scribbling them down during my commute and then looking them up later. Words are like jewels to me, each one as precious as the one before, and no two ever exactly the same, like snowflakes. Plus, words are the one thing you can never take away from me, not through poverty or old age or anything. Even if we couldn't speak or see, they'd stay richly, deeply rooted in our minds, echoing throughout between synapses, in the fertile soil that can never amass too many of them in its vastness.

    Sometimes, just for kicks, when I'm riding the train home from work, I take a blank paper journal page and write one word at the top. Then, I will write until I run out of ideas -- writing one word or phrase after another, which the initial word helps to spark inside my mind. In this way, I go on a kind of psychedelic word "trip," and, before I know it, I'm at my stop, which is a 40-minute ride to the end of the rail line and I'm feeling energized and full of new wonder.
