Make multiple languages available for your site’s user interface
As a site collection administrator, you can use the Multi-language user interface (MUI) feature to create sites in languages other than the default language for your site installation, and you can let individual users change the display language for their site’s user interface.

Make sure the language packs you need are installed
The list of available languages from which users can select the display language of their user interface is generated by the language packs that are installed on the front-end Web servers of your server farm.
Language packs must be installed by a server administrator—that is, someone who has the appropriate permission levels to download language packs onto your organization’s server computers.
Language packs provide language-specific translation of the following user interface elements.
Site settings interface
List and site column headers
Templates for new lists, document libraries, and sites
Managed metadata tagging.
Relevant search indexing of content that is not in the default language of the site.
After you make a language available, a user who is logged on to the site can select an alternative language in which to display the site for his or her own personal use.
Specify the languages you want to make available for the site’s user interface
As a site owner, after the language packs are deployed, do the following:
Click Site Actions, and then click Site Settings.
Under the Site Administration group, click Language Settings.
In the Alternate Language section, check the checkbox for the languages you want users to be able to use to display their user interfaces.
Now your users can change the display language for their personal use of the user interface.
After you turn on alternative languages for your site, you can create new lists or libraries in one language, then display the site in a different language, and modify the list or library name for that language. The same process works for list and library columns, and for navigation links.
With managed metadata, you can define multilingual term sets and share the taxonomy with multiple sites, site collections or farms.
