Ispell, Aspell and Hunspell use two dictionaries together for spell checking:
-the standard dictionary and your private dictionary. The variable
-@code{ispell-dictionary} specifies the file name to use for the
-standard dictionary; a value of @code{nil} selects the default
-dictionary. The command @kbd{M-x ispell-change-dictionary} sets this
-variable and then restarts the subprocess, so that it will use a
-different standard dictionary. A separate dictionary is used for word
-completion. The variable @code{ispell-complete-word-dict} specifies
-the file name of this dictionary. The completion dictionary must be
-different because it cannot use root and affix information. For some
-languages, there is a spell checking dictionary but no word completion
-dictionary.

+dictionary is specified by @code{ispell-local-dictionary} or,
