Add more languages and change the default proofing language

You can add more languages and change the default proofing language, by completing these procedures:

  1. Add a language pack

  2. Add a keyboard language

  3. Switch on Detect Language Automatically

    • When you complete these actions, the proofing tools automatically detect your language.

    • You don't need to complete these procedures in order, but we recommend it.

Add a language pack

You need to add a language pack for any languages you want used for spelling and grammar checks.

Before you can add a language pack, you need to make sure the language pack is already installed. You can tell that a language pack is installed when you see that Proofing installed displays next to the language name. 

  1. Go to Review > Language > Language preferences.

    In Outlook, you need to be editing or writing an email to access the Review tab.

  2. Complete one of the following:

  • If the desired language is installed but not added, select Proofing available next to the displayed name of the language on the list.

  • If the desired language is not installed, follow these steps:

    1. Select Add a language.

    2. Choose the desired language.

    3. Check Get proofing tools.

    4. Select Add.

To set a language as the default, select Preferred language > OK.

Changes made to the Office Authoring Language and Proofing list are applied to other Microsoft products in your account.

Add a keyboard language

 After adding a language pack, you need to add the keyboard language. For information on adding a keyboard language in Windows 11 and Windows 10, select Windows 11 or Windows 10 and follow the instructions.

The Microsoft Word proofing language changes to match the default Windows keyboard language. This can be switched on the Windows task bar.

Adding an input language lets you set a language-preference order for websites and apps, as well as change your keyboard language.

  1. Select Start > Settings > Time & language > Language & region.

  2. Select the language that has the keyboard you want, then select Options.

  3. Select Add a keyboard and choose the keyboard you want to add.

    If you don't see the keyboard you want, you may have to add a new language to get additional options. If this is the case, go to Add a language pack.
