How to Stop Word for Mac From Changing Proofing Language

Question details

The user needs to prevent Word for Mac from automatically overriding the selected English proofing language with foreign languages.

Product: Word for Mac
Device & OS: Mac
Scenario: Editing a text document where the proofing language keeps spontaneously shifting away from the user's intended language.
Observed behavior: Parts of the document automatically switch to Norwegian or Dutch, despite the user explicitly selecting all text and setting the language to English.

Before you start

Ensure you have saved your current document and take note of whether this issue occurs in a specific file or across all new documents, as pasted text often carries hidden language formatting.

Solution 1Recommended

Reset the Default Language and Apply to Selected Text

Manually re-apply the correct language to the entire document and enforce it as the default setting for future files to prevent unexpected shifts.

Word applies proofing languages at the character level. If portions of your document were previously formatted in another language, simply changing the overall document language might not override those specific sections without selecting them first.

Select all text in the document

Press Command + A on your keyboard to highlight all the text in your current document.

Open the Language settings

Navigate to the top menu bar, click on 'Tools', and then select 'Language' from the dropdown menu.

Choose your preferred English variant

Scroll through the list and select the specific English variant you need (e.g., English (US) or English (UK)).

Set as Default

Click the 'Default' button at the bottom of the dialog box if you want this language applied to all future documents based on the Normal template, then click 'OK'.

Automatic Detection: While in the Language dialog box, consider unchecking 'Detect language automatically' to stop Word from guessing the language as you type.

Solution 2

Check Document Styles and Pasted Content

Text-level language formatting from pasted content or paragraph styles can easily override the document's default language settings.

Frequently Asked Questions

Why does my Word document keep changing to another language?

Word can automatically detect language based on what you type, or it may retain the hidden language tags from text pasted from other sources like websites or foreign documents.

How do I stop Word from automatically detecting languages?

You can turn off automatic detection by going to Tools > Language and unchecking the 'Detect language automatically' option in the dialog box.

Does the Normal template affect my proofing language?

Yes, the Normal.dotm template stores default settings. If its default language is altered or corrupted, all new documents based on it will inherit the incorrect proofing language.

Will pasting text from websites change my language settings?

Yes, copying text from web pages often brings along its own HTML language formatting. To prevent this, always paste using the 'Keep Text Only' option.
