I would like vim spell to ignore words with Greek characters. Based on this question, I thought it might work to write :set spelllang+=cjk, but that did nothing. Apparently that only works for East Asian characters. Is there a comparable setting for Greek characters?

  • What does :help 'spelllang' say?

    FYI, cjk = Chinese Japanese Korean.

I would run the following command:

syntax match greekword /\<[α-ωΑ-Ω]\+\>/ contains=@NoSpell

It makes that the words that match the pattern (i.e.: are made entirely of Greek letters) are not checked for spelling error.

If you would like to have it automatically for all the LaTeX file (filetype: tex) you can add a dedicated syntax file to your configuration:


With the following content:

syntax match greekword /\<[α-ωΑ-Ω]\+\>/ contains=@NoSpell

If you want to take all the Greek letters you can do:

syntax match greekwork /[\u370-\u3ff\u1d26-\u1d6a\u1dbf\u1f00-\u1ffc\u213c-\u213f\u3382-\u33bc\uab65\U1d6a8-\U1d7cb]/ contains=@NoSpell

Remark: to simplify the pattern some additional characters has been included.

  • Thank you, but this didn't work for me. Could it be because I am using vimtex, which does a lot of syntax highlighting and such? Oct 12, 2023 at 11:09
  • Also: I am using neovim, in case that is relevant. Oct 12, 2023 at 11:17

    Yes, I just tried it again now, pasting in this exact command, and it still underlines the Greek words as if they were spelling errors. Oct 12, 2023 at 18:30

    Can you give an example of Greek word? Are they found by the following search /\<[α-ωΑ-Ω]\+\>? Oct 12, 2023 at 19:26

    I have updated the solution to take into account more Greek letters (hopefully all of them). Let me know if it works for you. Oct 13, 2023 at 14:26
