Today, however, I’m just talking about a spell-checker in Emacs: ispell. This spell-checker comes pre-installed if you’re running Emacs on Linux. Mac users may require some additional configuration.

Apparently, I use a lot of uncommon words in my writing. So the default ispell dictionary will often flag me for a word I spelled correctly! So it’s far from perfect.
That’s why Emacs gives you a nice variable: ispell-personal-dictionary. This variable accepts a file as a value. That file contains a list of words you have added to your personal dictionary.
And you don’t need to edit the file manually. You can add words to your dictionary right from Emacs.
