+The user's preferred locale.  The locale has six categories, specified
+by the environment variables @env{LC_COLLATE} for sorting,
+@env{LC_CTYPE} for character encoding, @env{LC_MESSAGES} for system
+messages, @env{LC_MONETARY} for monetary formats, @env{LC_NUMERIC} for

 matched against entries in @code{locale-language-names},
 @code{locale-charset-language-names}, and
 @code{locale-preferred-coding-systems}, to select a default language
