An authoring language influences text direction and layout for vertical, right-to-left, and mixed text. A display language determines the language Office uses in the UI - ribbon, buttons, dialog boxes, etc. You can add a display language or an authoring language.

The available languages depend on the language version of Office and any additional language pack, language interface pack, or ScreenTip languages that are installed on your computer.

For example, you could have everything match the language of your operating system, or you could use a combination of languages for your operating system, authoring, and Office UI display. The display and authoring languages can be set independently. The language options are in the Set the Office Language Preferences section of the Office Options dialog box, which you can access by going to File > Options > Language. You can use the Office language options to add a language, to choose the UI display language, and to set the authoring and proofing language.
