How to Spell Check in Neovim (nvim)

First, add the spell check in the init.vim file

" spell languages
set splelllang=en-gb

In the line above, we set the spell language to en-gb (UK English).

See a list of language codes.

Enable set spell in your configuration file

I don’t want to use spell check all the time, I set a toggle for this option in normal and insert mode.

(To silently execute a map, use the <silent> attribute for the map.)

nnoremap <silent> <F3> :set spell!<CR>
inoremap <silent> <F3> <C-O>:set spell!<CR>

Correcting spell errors in insert or normal mode

In insert mode, if you have typed some words which Vim thinks is miss-spelt, an underline is shown below the words. To correct the error, you can press <C-x> followed s. A completion menu will show a list of suggestions. You can then choose the correct one.

In normal mode, to navigate between the possible spell errors, use the following shortcut key:

• [s go to previous spell error
• ]s go to next spell error

If you think a word is not a spelling error, you can use zg to add the word to your spell list. To correct an error, use z=. A list of candidate words will be shown. You are prompted to enter a number to select the correct word.
