How to Spell Check with Vim

| posted in: nerdliness 

I have never been a good speller, therefore I rely on spell check to help ensure that my writing doesn’t contain basic spelling errors. Most modern software that is centered around text provides spell checking. However I do most of my writing, including all of the posts on, using Vim - a decidedly un-modern text editor.

Fortunately Vim is incredibly flexible and it is relatively straight-forward to enable spell checking.

##Enable spell checking You can turn spell checking on or off with

set spell
set nospell

##Default language The default language used is US English. You can change this to another language with

set spelllang=en_gb

The above example sets the language to British English.

In my .vimrc I have a number of file type specific settings, including spell checking. I only enable spell checking for a limited number of file types, as spell checking code isn’t very useful. The three autocmd entries I have are:

autocmd FileType mail setlocal spell spelllang=en_us
autocmd BufRead COMMIT_EDITMSG setlocal spell spelllang=en_us
autocmd BufNewFile,BufRead *.md,*.mkd,*.markdown set spell spelllang=en_us

The first is for when I’m using mutt for my mail - it turns spell checking on while I’m composing or replying to messages. The second activates spell check for Git commit messages. The last autocmd set spelling on for Markdown files.

##Your own dictionary It is possible to add words to your own dictionary using the zg key combination. You can undo the add with zug. It is also possible to mark a word as incorrectly spelled using zw. zuw undoes the incorrect marking.

##Find misspelled words You can jump forwards or backwards through the buffer to the next flagged work using


Once you’ve located a word, z= will bring up the list of suggested words, pick the associated number and press return and the new word will be substituted in for the old one.

##Help All of this and more can be found in the Vim help pages
