How to install a LibreOffice Dictionary (Spelling Check, Thesaurus…)

Question

What are the steps to install the Spelling Check and other language supports for LibreOffice. For example spanish, french, italian, etc..

Answer 1

This is apparently managed at the system level. Go to the Language Support menu in the System menu and add the languages you want to support. After that restart LibreOffice and you will see that the spellchecker for example will give you the option of using the newly installed languages.

Answer 2

The command: sudo apt-get install aspell-<language pack> will do the trick

For example, the spanish dictionary is:

sudo apt-get install aspell-es
