WORDS(5)                                                     Linux Programmers Manual                                                     WORDS(5)

NAME

       french - a list of french words

DESCRIPTION

       /usr/share/dict/french is an ASCII file which contains an alphabetic list of words, one per line.

FILES

       /etc/alternatives/dictionary  is  a  symbolic  link  to  a  /usr/share/dict/<language>  file.   /usr/share/dict/words is a symbolic link to
       /etc/alternatives/dictionary, and is the name by which other software should refer to the system word list.  See update-alternatives(8) for
       more information.

       The directory /usr/share/dict can contain word lists for many languages, with name of the language in English, e.g., /usr/share/dict/ameri-
       can-english and /usr/share/dict/danish contain respectively lists of English and Danish words if they exist.  Such lists  should  be  coded
       using the ISO 8859-1 character set encoding.

SEE ALSO

       ispell(1), update-alternatives(8), and the Filesystem Hierarchy Standard.

HISTORY

       The words lists are not specific, and may be generated from any number of sources.

AUTHOR

       Word lists are collected and maintained by various authors.
