The English language is not meant to be fun. A doctoral degree is best used as a tool for intimidation. And for god’s sake, a publishing contract is not a license to let the hoi polloi think they know something—even if it’s only about anagrams, palindromes, and “letter play.” Richard Lederer will break all these rules and more, as well as sign his latest load of fodder for the fatuous, Word Circus (wherein readers are invited to see the alphabet “leap” and “pirouette”), when he comes to the Smithsonian to preach to other self-professed “wordaholics, logolepts, and verbivores.” Distinguish yourself from these disciples at 6 p.m. at the Museum of Natural History’s Baird Auditorium, 10th & Constitution Ave. NW. $13. For reservations call (202) 357-3030. (Caroline Schweiter)
