How may I add additional languages to the user's interface?

I’m using LibreOffice in English and Spanish, the Interface allow me to chose between US English and Spanish
Tools… Options… Language Settings… Languages
and there User Interface
However I’d need to use LibreOffice also in Russian, so I’d need to add an aditional language to the user’s interface, in that way I can see the menus in other language as Russian.
How may I add an additional language for the user interface?

Application of LibO for English, Japanese, German and Dutch; switching between languages is done very frequently.

Installation:English US version because I learned somewhere that this is the multi-language version.
The GUI is English but the installation foresees also a switch to Japanese GUI however, until now I never had to switch to Japanese GUI
Dictionaries are installed for all languages.

This means you should be able to do get an equivalent installation for the languages you need. When you install LIbO I recommend to make a customized installation and select the languages you need. Once you did this for your first or next installation, the upgrades automatically install in the same customized way.

As far as I remember, selecting your languages means deselecting all the others. Just have a careful look when you make the first multi-language installation. It might be good to re-install LibO again and make sure that the languages you need are included and all the others are out.

For me this works very well since about 3.5.4 (first installation) and now I am running 3.5.7 and intend to change to 3.6.4 when this is released next month.

user interface = UI = GUI = graphical user interface
differentiate between UI/GUI and languages. I described languages by using the term dictionaries where languages might have been the better term.

in tools>options>languages you only need to select your
default UI
default local settings

default Western (language). You don’t need to do anything for Asian (language) or CTL (language) You can leave their what pops up.

Hello, IT’S ME THE ONE WHO ASKED THIS (but initially I asked this as anonymous I don’t know why).
Thanks for your reply but I am not an advanced user and I don’t understand anything. I am in Windows, and I don’t know what is LibO, what function it does, and if I should install that or not, and also I don’t know how to install it? When I installed LibreOffice I installed it in Spanish (I am in Spain) and it has by defualt to languages… Spanish and US English. What I need is to install an additional language, this case, Russian. How may I do this step by step in an easy way? Thanks

During the installation process… you can installa additional languages…

Could I run again the installation of LibreOffice to install new laguages?
What may I do to install new languages for the User Interface?

LibO = LibreOffice = LO

You can re-install LibO and you should be able to check if you can install all languages when installing the Spanish version. As far as I know the UI becomes than automatically Spanish.

Follow the procedure on the link you found already.

Setup Type: select Custom

Then look into Optional Components (if I remember correct this is where other languages are in) for other languages/dictionaries. If you don’t find English and Russian you can try the English US version, this version includes all or almost all languages.

If you don’t need another UI language you can leave you can leave Additional User Interfaces untouched.

Good luck!

See also → The langauge for the user interface only gives one option - french ( the operating system language). However I\the user wishes it to be in Dutch. how can I increase the choices available for this option?

It seems that to be able to select the document language (tools->language->for all text->givenLang) I had to reboot my computer (linux debian), maybe restarting only the display manager would have been enough

  1. Go to
  2. Select your version of LibreOffice.
  3. Download the language and help packages you want, and install it. Installation instructions for Linux, Mac and Windows.

You may need to copy/move the installed files to the place where your default (repo) LibreOffice is installed. For example, on Linux, the downloaded files are usually installed to /opt/libreoffice whereas the default (repository) installation of LibreOffice is in /usr/lib/libreoffice or /usr/lib64/libreoffice or /usr/share/libreoffice.
