Enable Automatic Language Detection in Word
Configure the proofing language settings to allow Microsoft Word to automatically identify the language you are typing.
Microsoft Word requires explicit permission to detect languages automatically. Keep in mind that this feature works best when there is enough context—usually at least a full sentence—for the application to accurately determine the language.
Open Microsoft Word and navigate to the 'Review' tab located on the top ribbon menu.
Click on 'Language' in the ribbon, and then select 'Set Proofing Language' from the dropdown menu.
In the Language dialog box, check the box labeled 'Detect language automatically'.
Click 'OK' to save your settings. You may need to restart the Office application for the changes to fully take effect.
Manually Assign the Proofing Language
When automatic detection fails due to short text or mixed languages, manually apply the correct proofing language to your selected text.

Frequently Asked Questions
Why is Word spell check detecting the wrong language while I type?
Automatic language detection relies heavily on context and sentence length. If you type short phrases or frequently mix languages within the same sentence, the application may fail to identify the correct language reliably.
Do I need to download proofing tools for every language in Office?
Yes. In order for the spell check and grammar tools to function properly, you must have the specific language accessory pack and corresponding proofing tools installed for each language you wish to use.
How do I fix spell check not working for emails in Outlook?
While composing an email in Outlook, go to the Review tab, select Language, and then click Set Proofing Language. Ensure the correct language is highlighted and that the 'Do not check spelling or grammar' option is unchecked.
