How do I add English-UK thesaurus and other locales to LibreOffice?

Solution 1:

Here's what worked for me. I found most of these steps in this blog post, credit to the author for figuring this out.

1. Download the spelling/hyphen/thesaurus dictionaries you want from LibreOffice's extensions download page.
2. Install them in LibreOffice Tools -> Extension Manager -> Add and then close LibreOffice.
3. sudo apt-get install libmythes-1.2-0 hunspell
4. sudo apt-get install mythes-en-us hunspell-en-us
5. cd /usr/share/mythes/
6. sudo ln -s th_en_US_v2.idx th_en_GB_v2.idx
7. sudo ln -s th_en_US_v2.dat th_en_GB_v2.dat
8. Open LibreOffice Writer and go to Tools -> Options -> Language Settings -> Writing Aids.
9. Verify the new thesaurus is selected, then from Writer test it by pressing Ctrl + F7 to bring up the thesaurus dialogue.

Solution 2:

This latest version of the Libreoffice Extension "English Dictionaries" works with the latest version of Libreoffice and will hopefully get the thesaurus activated for you.

Solution 3:

With each installation of Libreoffice on any of the Distros I have installed for myself or others I have found that the thesaurus always works after I have installed the English dictionaries for Apache OpenOffice-2013.07.31 rather than any extension from LibreOffice.

This makes all the above solutions unnecessary.

This OpenOffice dictionary extension is a year old now and although there are more recent versions here English dictionaries for Apache OpenOffice they always give the error

Extension requires at least OpenOffice.org reference version 4.0

when I attempt to install them.

Solution 4:

• For English-UK, the correct answer is in Mik's

I am posting this answer for other locales:

So:

• For French, go here to get the French dictionary and install in LibreOffice Writer in Tools-Extensions manager. (The spelling works before installing that, but synonyms context menu does not).
