### Other Lexicon Conventions

Entries are sorted in case-blind ASCII collation order (rather than the letter-by-letter order ignoring interword spacing common in mainstream dictionaries), except that all entries beginning with nonalphabetic characters are sorted before A. The case-blindness is a feature, not a bug.

The beginning of each entry is marked by a colon (`:`) at the left margin. This convention helps out tools like hypertext browsers that benefit from knowing where entry boundaries are, but aren't as context-sensitive as humans.

In pure ASCII renderings of the Jargon File, you will see {} used to bracket words which themselves have entries in the File. This isn't done all the time for every such word, but it is done everywhere that a reminder seems useful that the term has a jargon meaning and one might wish to refer to its entry.

In this all-ASCII version, headwords for topic entries are distinguished from those for ordinary entries by being followed by "::" rather than ":"; similarly, references are surrounded by "{{" and "}}" rather than "{" and "}".

Defining instances of terms and phrases appear in `slanted type'. A defining instance is one which occurs near to or as part of an explanation of it.

Prefix ** is used as linguists do; to mark examples of incorrect usage.

We follow the `logical' quoting convention described in the Writing Style section above. In addition, we reserve double quotes for actual excerpts of text or (sometimes invented) speech. Scare quotes (which mark a word being used in a nonstandard way), and philosopher's quotes (which turn an utterance into the string of letters or words that name it) are both rendered with single quotes.

References such as `malloc(3)` and `patch(1)` are to Unix facilities (some of which, such as `patch(1)`, are actually open source distributed over Usenet). The Unix manuals use `foo(n)` to refer to item foo in section (n) of the manual, where n=1 is utilities, n=2 is system calls, n=3 is C library routines, n=6 is games, and n=8 (where present) is system administration utilities. Sections 4, 5, and 7 of the manuals have changed roles frequently and in any case are not referred to in any of the entries.

Various abbreviations used frequently in the lexicon are summarized here:

abbrev.
  abbreviation
adj.
  adjective
adv.
  adverb
alt.
  alternate
cav.
  caveat
conj.
  conjunction
esp.
  especially
excl.
  exclamation
imp.
  imperative
interj.
  interjection
n.
  noun
obs.
  obsolete
pl.
  plural
poss.
  possibly
pref.
  prefix
prob.
  probably
prov.
  proverbial
quant.
  quantifier
suff.
  suffix
syn.
  synonym (or synonymous with)
v.
  verb (may be transitive or intransitive)
var.
  variant
vi.
  intransitive verb
vt.
  transitive verb

Where alternate spellings or pronunciations are given, alt. separates two possibilities with nearly equal distribution, while var. prefixes one that is markedly less common than the primary.

Where a term can be attributed to a particular subculture or is known to have originated there, we have tried to so indicate. Here is a list of abbreviations used in etymologies:

Amateur Packet Radio
  A technical culture of ham-radio sites using AX.25 and TCP/IP for wide-area networking and BBS systems.
Berkeley
  University of California at Berkeley
BBN
  Bolt, Beranek & Newman
Cambridge
  the university in England (not the city in Massachusetts where MIT happens to be located!)
CMU
  Carnegie-Mellon University
Commodore
  Commodore Business Machines
DEC
  The Digital Equipment Corporation (now Compaq).
Fairchild
  The Fairchild Instruments Palo Alto development group
FidoNet
  See the FidoNet entry

  Some MITisms go back as far as the Tech Model Railroad Club (TMRC) at MIT c. 1960. Material marked TMRC is from "An Abridged Dictionary of the TMRC Language", originally compiled by Pete Samson in 1959
UCLA
  University of California at Los Angeles

  XEROX's Palo Alto Research Center, site of much pioneering research in user interface design and networking
Yale
  Yale University

Some other etymology abbreviations such as Unix and PDP-10 refer to technical cultures surrounding specific operating systems, processors, or other environments. The fact that a term is labelled with any one of these abbreviations does not necessarily mean its use is confined to that culture. In particular, many terms labelled `MIT' and `Stanford' are in quite general use. We have tried to give some indication of the distribution of speakers in the usage notes; however, a number of factors mentioned in the introduction conspire to make these indications less definite than might be desirable.

A few new definitions attached to entries are marked [proposed]. These are usually generalizations suggested by editors or Usenet respondents in the process of commenting on previous definitions of those entries. These are not represented as established jargon.
