From the ubuntu libreoffice-l10n-en-gb package description: Spelling dictionaries, hyphenation patterns, thesauri and help are not included in this package. There are some available in separate packages (myspell-*, hyphen-*, mythes-*, libreoffice-help-*) then search for mythes in ubuntu repository, suitable for the release you have installed.
A thesaurus IS available IF Set Tools > Options > Languages & Locales > General > Default Language for Documents > Western = English (US) or other language variant. When researching this issue, there are no clear/user friendly methods to gain access to a British thesaurus. For example when attempting: $ sudo apt install mythes-en-gb Reading package lists... Done Building dependency tree... Done Reading state information... Done Package mythes-en-gb is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'mythes-en-gb' has no installation candidate
It's not LO pb but distrib pb, see https://bugs.documentfoundation.org/show_bug.cgi?id=48340 + https://bugs.launchpad.net/ubuntu/+source/openoffice.org-dictionaries/+bug/950949 I read quickly but it seems that installing mythes-en-us may help since it'd contain both en-us + en-gb but not sure if it's still the case in 2025. *** This bug has been marked as a duplicate of bug 48340 ***
