How to Spell-Check Multiple Languages in Word on Windows 10
Product
Microsoft Word
Device & OS
Windows 10
Scenario
Writing a multilingual document and needing the word processor to accurately spell-check languages other than the default system language.
Observed behavior
Microsoft Word requires specific proofing tools to be installed and the text to be explicitly marked with the target language for the spell-checker to recognize and evaluate it correctly.
Before you start

Ensure your computer is connected to the internet, as you may need to download additional Office language accessory packs to enable proofing tools for new languages.

Set Proofing Language and Install Office Accessory Pack in Word

Directly assign the correct language to your text within Word and ensure the required proofing tools are downloaded.

Microsoft Word has its own spell-checking engine that operates independently of the Windows system language limit. You can check spelling in dozens of languages within a single document by marking specific text selections.

1
Select the target text

Highlight the specific text in your Word document that is written in the alternate language (e.g., Portuguese).

2
Navigate to the Language settings

Go to the 'Review' tab on the top ribbon, click the 'Language' button, and select 'Set Proofing Language' from the dropdown menu.

3
Choose the language and install tools

Scroll through the list and select your target language. If the language has a 'Proofing available' icon missing, you may be prompted to download the Microsoft Office language accessory pack. Follow the prompts to install it.

4
Restart and verify

After the language tools finish installing, restart Microsoft Word. Return to your document and verify that the spell-checker now properly highlights errors for that language.

Frequently Asked Questions

Is there a limit to how many languages I can spell-check in Word?

No, there is no inherent limit to the number of languages you can spell-check. Microsoft Word can handle multiple languages within the same document as long as the respective proofing tools are installed and the text blocks are marked with the correct languages.

Why is Word marking all my foreign language text as misspelled?

This usually happens because Word is applying your default language dictionary (e.g., English) to the foreign text. To fix it, highlight the text, go to Review > Language > Set Proofing Language, and choose the correct language for that text.

Do I need to install a Windows language pack or an Office language pack?

Microsoft Word primarily uses its own Office Language Accessory Packs for proofing. However, installing the language in Windows 10 under Time & Language > Language is highly recommended for OS-level spell-check support and overall stability.
