A recursive acronym is an acronym that refers to itself. The term was first used in print in 1979 in Douglas Hofstadter's book Gödel, Escher, Bach: An Eternal Golden Braid, in which Hofstadter invents the acronym GOD, meaning "GOD Over Djinn", to help explain infinite series, and describes it as a recursive acronym. [1] Other references followed, [2] however the concept was used as early as 1968 in John Brunner's science fiction novel Stand On Zanzibar. In the story, the acronym EPT (Education for Particular Task) later morphed into "Eptification for Particular Task".

Computer-related examples

In computing, an early tradition in the hacker community (especially at MIT) was to choose acronyms and abbreviations that referred humorously to themselves or to other abbreviations. Perhaps the earliest example in this context, from about 1977 or 1978, is TINT ("TINT Is Not TECO"), an editor for MagicSix written (and named) by Ted Anderson. This inspired the two MIT Lisp Machine editors called EINE ("EINE Is Not Emacs") and ZWEI ("ZWEI Was EINE Initially"). These were followed by Richard Stallman's GNU (GNU's Not Unix). Many others also include negatives, such as denials that the thing defined is or resembles something else (which the thing defined does in fact resemble or is even derived from), to indicate that, despite the similarities, it was distinct from the program on which it was based.[3]

An earlier example appears in a 1976 textbook on data structures, in which the pseudo-language SPARKS is used to define the algorithms discussed in the text. "SPARKS" is claimed to be a non-acronymic name, but "several cute ideas have been suggested" as expansions of the name. One of the suggestions is "Smart Programmers Are Required to Know SPARKS".[4]

Mutually recursive or otherwise special

  • The GNU Hurd project is named with a mutually recursive acronym: "Hurd" stands for "Hird of Unix-Replacing Daemons", and "Hird" stands for "Hurd of Interfaces Representing Depth."
  • RPM, PHP, XBMC and YAML were originally conventional acronyms which were later redefined recursively. They are examples of, or may be referred to as, backronymization,[citation needed] where the official meaning of an acronym is changed.
  • Jini claims the distinction of being the first recursive anti-acronym: 'Jini Is Not Initials'.[17][18] It might, however, be more properly termed an anti-backronym because the term "Jini" never stood for anything in the first place. The more recent "XNA", on the other hand, was deliberately designed that way.
  • Most recursive acronyms are recursive on the first letter, which is therefore an arbitrary choice, often selected for reasons of humour, ease of pronunciation, or consistency with an earlier acronym that used the same letters for different words, such as PHP: PHP Hypertext Preprocessor, which was originally "Personal home page". However YOPY, "Your own personal YOPY" is recursive on the last letter (hence the last letter of the acronym had to be the same as the first).

Some organizations have been named or renamed in this way:

  • BWIA — BWIA West Indies Airways (formerly British West Indian Airways)
  • FALE — Fale Association of Locksport Enthusiasts[19][20]

  • LINK — Link Interchange NetworK, the UK ATM switching organization.
  • Heil — Heil Environmental Industries Limited, maker of garbage trucks
  • Saab — Saab Aeroplan Aktiebolaget (originally Svenska Aeroplan Aktiebolaget)

In popular culture

  • TTP - a technology project in the Dilbert comic strip. The initials stand for "The TTP Project".
