Spell Checking is done by Emacs by calling external spell checkers.

Basic setup

You need to install either aspell or hunspell.

On GNU/Linux

Links to pre compiled binaries are dead at time of writing.

I got RPMs from [http://download.opensuse.org/repositories/windows:/mingw:/win32/openSUSE_Factory/noarch/ openSUSE], but hunspell.exe aborted after not finding a dll file. After that dll was added, another dll was not found. I gave up after several iterations. This was with mingw32-hunspell-1.3.2-1.98.noarch.rpm and later mingw32-hunspell-1.3.2-1.99.noarch.rpm (and associated lang and tools RPMs). Windows users be aware of this.

Useful commands

M-x ispell-change-dictionary RET SPC
Check list of installed dictionaries.
M-x customize-variable RET ispell-dictionary
Configure default dictionary.
M-x add-file-local-variable RET ispell-dictionary RET TAB
Use this to change dictionary on per-file basis. This command will add this line to the file in question. Please save and re-load the file for new settings to take effect.
  -*- ispell-dictionary: "english" -*-

Common Customization


You need dictionary files for spell check to work. If you have installed OpenOffice or LibreOffice, then dictionary files are already there.

(setq-default ispell-program-name "hunspell")
