How to Spell-Check Multiple Languages in Word on Windows 10
Question details
The user wants to know if Windows 10 and Microsoft Word can spell-check more than two languages and how to enable Portuguese spell-checking.

- 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.
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.
Highlight the specific text in your Word document that is written in the alternate language (e.g., Portuguese).
Go to the 'Review' tab on the top ribbon, click the 'Language' button, and select 'Set Proofing Language' from the dropdown menu.
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.
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.

Add the Target Language in Windows 10 Settings
Install the language pack in your Windows system settings to ensure broader OS-level compatibility and dictionary support.

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.
