Scenario
Typing notes or documents and relying on the built-in spell checker to catch errors, but receiving foreign language suggestions instead of English ones.

Before modifying app settings, verify that your device's system keyboard is currently set to your preferred language and that you haven't accidentally toggled to a foreign language layout while typing.

Solution 1Recommended

Reset the iOS Keyboard Spell Check Settings

Since Word and OneNote on iOS rely on system-level keyboard features, toggling the global spell check off and on can resolve language confusion.

Mobile versions of Microsoft Office applications frequently pull their proofing tools directly from the iOS keyboard settings. If the system spell checker gets stuck or confused, resetting it from the main settings app will force it to recalibrate to your active keyboard language.

1
Open iOS Settings

Navigate to the home screen of your iPhone or iPad and open the 'Settings' app.

2
Navigate to Keyboard Settings

Scroll down and tap on 'General', then select 'Keyboard' to access your typing and language preferences.

3
Toggle Check Spelling

Locate the 'Check Spelling' switch. Tap it to turn it off, wait a few seconds, and then tap it again to turn it back on.

4
Verify Active Keyboards

Tap 'Keyboards' at the top of the menu and ensure your desired language (e.g., English) is listed at the top. Remove any unnecessary foreign language keyboards.

Reset the iOS Keyboard Spell Check Settings
System-Wide Application: Applying this fix will correct the spell check behavior not only in Word and OneNote but across all apps on your iOS device.

Frequently Asked Questions

Why is my spell check suddenly in a different language?

This usually happens if your keyboard language was accidentally switched via a shortcut, or if you pasted text from another source that carried over its original proofing language formatting into your current document.

How do I change the default proofing language in Microsoft Word?

In Word, highlight your text, go to the 'Review' tab, select 'Language', and then click 'Set Proofing Language'. Choose your preferred language, click 'Set As Default', and confirm to apply it to all new documents.

Does WPS Office support multiple languages for spell checking?

Yes, WPS Office supports spell checking in numerous languages. You can easily switch the dictionary language from the 'Review' tab to match the text you are currently writing, preventing false error highlights.
