History

Etymology

A reverse spelling of palindromes. "Semordnilap", according to author O. V. Michaelsen in his 1997 book Words at Play, was probably first used by recreational linguist Dmitri Borgmann, cited by Martin Gardner in the revised edition of Charles Carroll Bombaugh's Oddities and Curiosities of Words and Literature (1961) http://books.google.com/books?id=f4kNAQAAIAAJ&q=borgmann. The underlying concept (but not the term) is found at least as far back as Lewis Carroll's Sylvie and Bruno (1889). Semordnilap is also autological; that is, it is a self-describing word, as the word semordnilap is itself a semordnilap.
