Device & OS: not provided

Solution 1Recommended

Disable Automatic Keyboard Switching in Word Options

Turn off the advanced setting that allows Office to automatically switch the proofing language based on the surrounding text or keyboard locale.

By default, Office tries to be helpful by matching your spelling dictionary to your active keyboard layout. Disabling this feature ensures that your spell-checker remains locked to your chosen language, regardless of keyboard input changes.

Open Word Options

Launch Microsoft Word. Click on 'File' in the top-left corner of the ribbon, then select 'Options' at the very bottom of the left-hand menu.

Navigate to Advanced Settings

In the Word Options dialog box, click on the 'Advanced' tab located in the left sidebar.

Disable Automatic Switching

Scroll down to the 'Editing options' section. Find and uncheck the box labeled 'Automatically switch keyboard to match language of surrounding text'.

Save and Apply

Click 'OK' at the bottom of the dialog box to save your changes. This setting will generally carry over to PowerPoint as well.

Frequently Asked Questions

Why does my spell check language keep changing randomly?

This usually happens because Office is configured to automatically detect the language of the surrounding text or match the language of your current keyboard layout. Disabling the 'Automatically switch keyboard' setting stops this behavior.

How do I set a default proofing language for all new documents?

Go to the Review tab on the ribbon, click 'Language', and select 'Set Proofing Language'. Choose your preferred language from the list, click 'Set As Default', and confirm the prompt to apply it to the Normal template.

Does disabling this setting in Word fix the issue in PowerPoint?

Yes, many core editing and language preferences are shared across the Microsoft Office suite. Adjusting the advanced keyboard switching setting in Word will typically stop the proofing language from changing automatically in PowerPoint.
