I've ordered my copy, but I'm waiting for someone—someone who is slightly more obsessed with words than I am—to go through and publish an online list of what those 5,000 new words are, because I'm sure as heck not starting over. Plan on a few additional posts at the end of the year.
It's true that at this point in the year I'm thinking longingly of all the extra time I'll have next year, but as soon as I start reading, time doesn't matter, and the words soak into me like hot, soothing water in a tub . . . everyone has additions. There are good addictions and bad addictions. And if I gotta choose, I choose logophilia. Bring it on, Fifth Edition!
