NAME
american-english-large - a list of English words DESCRIPTION
/usr/share/dict/american-english-large is an ASCII file which contains an alphabetic list of words, one per line. FILES
There may be any number of word lists in /usr/share/dict/. /etc/dictionaries-common/words is a symbolic link to the currently-chosen /usr/share/dict/<language> file. /usr/share/dict/words is a symbolic link to /etc/dictionaries-common/words, and is the name by which other software should refer to the system word list. See select-default-wordlist(8) for more information, and/or to change the currently- chosen word list. The directory /usr/share/dict can contain word lists for many languages, with name of the language in English, e.g., /usr/share/dict/french and /usr/share/dict/danish contain respectively lists of French and Danish words if they exist. Such lists should be coded using the ISO 8859-1 character set encoding. SEE ALSO
ispell(1), select-default-wordlist(8), and the Filesystem Hierarchy Standard. HISTORY
The words lists are not specific, and may be generated from any number of sources. The system word list used to be /usr/dict/words. For compatibility, software should check that location if /usr/share/dict/words does not exist. AUTHOR
Word lists are collected and maintained by various authors. The Debian English word lists are built from the SCOWL (Spell- Checker Ori- ented Word Lists) package, whose upstream editor is Kevin Atkinson <kevina@users.sourceforge.net>. Debian 16 June 2003 american-english-large(5)
