Question details

The user needs to prevent Microsoft Word and PowerPoint on Mac from automatically changing selected proofing languages and disabling the spell check feature.

Product: Microsoft Word and PowerPoint for Mac
Device & OS: macOS
Scenario: Creating or editing multilingual documents and presentations where specific sections need different proofing languages.
Observed behavior: Language settings frequently revert to English. The automatic language detection fails, and the 'Do not check spelling or grammar' option gets enabled by itself when selecting other languages like Swedish.

Before you start

Before modifying your formatting settings, ensure your Microsoft Office applications are updated to the latest version and verify that the macOS system keyboard settings include the languages you intend to type in.

Solution 1Recommended

Apply Proofing Languages Using Custom Text Styles

Instead of changing the default language manually, assign specific languages to custom text styles to ensure stable spell checking for multilingual documents.

Because automatic language detection on Mac is often unreliable, the most stable method for multilingual documents is creating dedicated styles for each language. This prevents the primary body style from constantly overriding your manual language choices.

Open Style Pane

In Microsoft Word, go to the 'Home' tab and click on the 'Styles Pane' button to open the styles menu on the right side of your screen.

Create a New Style

Click 'New Style', name it according to your target language (e.g., 'Body - Swedish'), and base it on the 'Normal' style.

Assign Language to Style

In the new style dialog, click 'Format' in the bottom-left corner, select 'Language', choose your desired language (e.g., Swedish), and click 'OK'.

Apply Style to Text

Select the specific portions of text written in that language and click your newly created style in the Styles Pane to apply the correct proofing settings.

Best Practice: Keep your 'Normal' style set to the language you use most frequently, and only use custom styles for secondary languages.

Solution 2

Manually Override 'Do Not Check Spelling' Setting

Fix sections of text where PowerPoint or Word has automatically disabled the spell checker.

Solution 3

Use Separate Templates for Different Languages

If you write entire documents in a single foreign language, using specialized templates prevents language conflicts altogether.

Frequently Asked Questions

Why does Word for Mac keep changing my proofing language to English?

This usually happens because Word's 'Detect language automatically' feature often misidentifies text. When it gets confused, it falls back to your system's default language (typically English) or applies the primary 'Normal' style setting.

How do I stop PowerPoint from disabling spell check on certain languages?

Select the affected text box, go to Tools > Language in the top menu, and make sure the 'Do not check spelling or grammar' option is unchecked while your desired language is highlighted.

Is it better to change the default language or use custom styles for multilingual documents?

It is better to use custom styles. Changing the default language of your primary style affects the entire document and often leads to formatting conflicts. Creating separate styles (e.g., 'Body - English' and 'Body - Swedish') provides much more reliable spell checking.
