There are three areas in Microsoft Office where you may want to change the language.

• Editing or Authoring is the language in which you write and edit your content. You may need to install an associated keyboard for this language via Windows settings.

• Proofing tools are spelling and grammar check. Typically, you'll set this language to be the same as the editing or authoring language.

• Display language is for all the buttons, menus, and controls in Office.

You can set the display and editing or authoring languages independently from each other. For example, you may want the display language to be English, but the document you're writing or editing is in French.

On the following page describes Microsoft how you can change the language for these different areas: Change the language Office uses in its menus and proofing tools (microsoft.com)
