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.
