Locale Service Properties 
The portal supports the translation of its UI text strings from its default language to any language supported by the locale service. The locale service properties determine what languages comprise the master language list, to which languages the UI strings may be translated, and which languages are available for translation to users logged on to the portal as anonymous users.
