NAME
canadian-english-huge - a list of English words
DESCRIPTION
/usr/share/dict/canadian-english-huge 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>.
