How to Enable Automatic Spelling and Grammar Check in LibreOffice Writer

Here’s how you can enable automatic spelling and grammar checks as you type in LibreOffice Writer.

LibreOffice Writer supports multiple language dictionaries that are used to validate the grammar of the words as you type alongside spelling. The Writer shows a red colour curved line under the incorrect word in the document after it validates against the supported dictionary. Grammar errors are shown in blue, curved, and underlined against phrases.

How to Enable Automatic Spelling and Grammar Check

There are two ways to check spelling and grammar.

A) Manual mode and B) Automatic Mode as you type.

To enable the automatic spelling and grammar check, go to Menu Tools > Options. For macOS choose, LibreOffice > Preferences.

From the left pane, select Language under Language Settings. Choose the appropriate language under “Default Languages for Documents” – e.g. Western: English (USA).

Options - Language Settings - Writer

Go to Writing Aids Option to the left, and under options, choose ‘Check spelling as you type’ and ‘Check grammar as you type’.

Options - Language Settings - Writing Aids

Press OK.

Now you can see red curly underlines on words that have spelling errors.

Using LanguageTool

LanguageTool is a popular multi-multilanguage spelling, style and grammar checker which helps you to correct and paraphrase texts. It’s one of the best “free” alternatives to Grammarly – which is also a popular service.

It comes with two options. The free option comes with basic style, grammar, semantics, and a few preliminary features. And the premium version gives you more options.

  • Open LibreOffice (any module such as Writer, Calc, etc.)
  • From the menu, select Tools > Options. For macOS users, choose LibreOffice > Preferences.
  • On the options window, select Language Settings > LanguageTool Server. This option is available on LibreOffice 7.4 and above.
  • Select the checkbox Enable LanguageTool.
  • Make sure the base URL is https://api.languagetool.org/v2
  • (optional for premium) If you have a LanguageTool Premium account, copy and paste https://api.languagetoolplus.com/v2 in “Base URL,” write your email address, and type in the API key. You can generate this yourself by clicking on “Access token” in the settings of the LanguageTool Editor. There you will find the option for LibreOffice.
  • Click apply.
  • Select Language Settings > Writing aids on the left panel in the same options window.
  • Enable LanguageTool Remote Grammar Checker under Available Language Modules.
  • Hit Apply & close.
  • From the menu, select Tools > Automatic Spell checking.
  • And that’s it, you should see the suggestions as you type in your document.

No. The grammar checker does NOT work. Period.

Lea Stanke

Agree. The spell checker does work, but the grammar checker does not.
I use the British English language because I study in the UK, so I need to hand in all work in BE. For British English, the grammar checker does not work.
For example if you repeat a word “The the dog …” libre office doesn’t notice it.
If you use American English instead of British English “utilize” vs “utilise”, libre office doesn’t notice it.
This is really problematic for me.

This didn’t work for me. I still don’t have any red squiggly lines even though I did what you said. Thanks,
