 Humor writer Paul Jennings had published made-up meanings of real place-names in a 1963 essay appearing in "The Jenguin Pennings".Author Douglas Adams, while travelling with British comedy producer John Lloyd, suggested they play a game he had learned at school in which players were challenged to make up plausible word definitions for place names taken from road maps; the definitions they came up with were later incorporated into a 1983 book, "The Meaning of Liff".The similarities and relationship between the content of this book and the Hall concept of sniglets is noted, by Barbara Wallraff, in "Word Court" (2001).
