Here’s how you can use Thesaurus in LibreOffice and how to install them as well for various languages.

What is Thesaurus?

In a very generic term, a thesaurus is a synonym dictionary which helps you find similar words while writing or your professional work.

Everyone needs a good vocabulary for a strong writing piece if you are an author, writer, journalist, student or researcher. It is often crucial for many users across various work of jobs. Hence, we use Thesaurus for these needs.

How to Use Default Thesaurus in LibreOffice

Since it deals with synonyms, dictionaries differ for various language types. Take English, for example. The dictionary for US English is different from UK or Australian English. Also, the French dictionary will be completely different.

The Thesaurus should be enabled by default if you have installed LibreOffice in English.

To find out about your default Language, check at the bottom of the LibreOffice window (Calc, Writer, etc.), and you should see something like this.

Now, it’s time to see the Thesaurus features.

  • Then choose Right Click > Synonyms.
  • Thesaurus feature is enabled by default in LibreOffice if the Synonym option is available.

You can also bring up the window using CTRL+F7. Or using Tools > Thesaurus from the menu.

Additional Notes, Tips and Troubleshooting

The following notes I have collected across the web to help you on various issues related to Thesaurus.

  • If the Tools > Thesaurus option is greyed out (i.e. disabled), then for Linux systems, run the following command from the terminal (CTRL+ALT+T) to install the package.
sudo apt install mythes-en-us
  • You can see “en-us” in the above command at the end. That denotes English (en) and USA (us). Hence you can modify this based on your language and locale needs. You can find a sample ISO language code list here.
  • For example, for the UK, the command would be:
sudo apt install mythes-en-gb
  • After you install the package, restart your computer and check.
  • Linux systems stores the Thesaurus and languages in the following directories.
/usr/share/mythes
/usr/share/myspell

  • As shown below, you can install additional languages from the navigation Tools > Options > Language Settings > Writing Aids.
