Inspired by John Meyer's challenge in "A Positional Word List" in the May 1978 Word Ways, I decided to look for nine-letter words in which the central letter takes each alphabetical value, and both four-letter ends are words. Finding this task too easy for most central letters, I decided to restrict myself to nonpattern words. This proved impossible for only J and Z; for Q, I was unable to find any suitable nine-letter word, even allowing repeated letters.
