How to Stop Word for Mac from Changing Language to Scottish Gaelic
Product
Microsoft Word for Mac
Device & OS
macOS
Scenario
Typing text or opening new and existing documents in Microsoft Word.
Observed behavior
The language automatically defaults to Scottish Gaelic, often ignoring the user's intended primary language. This is frequently triggered by having the Irish Extended keyboard input source enabled in macOS.
Before you start

Save your current work and close all active Microsoft Office applications before modifying macOS system preferences or resetting application containers.

Solution 1Recommended

Remove Conflicting macOS Keyboard Input Sources

Removing the Irish Extended input source from your Mac's system settings prevents Word from misinterpreting the keyboard layout as Scottish Gaelic.

macOS keyboard input sources directly communicate with Microsoft Word to set the proofing language. When 'Irish Extended' is enabled, Word frequently misidentifies the intended language as Scottish Gaelic.

1
Open System Preferences

Click the Apple menu in the top-left corner of your screen and select 'System Preferences' (or 'System Settings' on newer macOS versions).

2
Navigate to Keyboard Settings

Click on 'Keyboard' and then navigate to the 'Input Sources' tab.

3
Remove Irish Extended

Look for 'Irish Extended' in the list of active input sources. Select it, and click the minus (-) button at the bottom of the list to remove it.

Restart Required: After removing the input source, restart Microsoft Word for the new settings to take effect completely.

Frequently Asked Questions

Why does the language only change to Scottish Gaelic in my existing documents?

If new documents are fine but existing ones are not, the Scottish Gaelic language setting may be hardcoded into the 'Normal' style of those specific files. You will need to open each affected document, modify the Normal style settings individually, and correct the language.

Does starting my Mac in Safe Mode fix the Word language bug permanently?

No, Safe Mode is a diagnostic tool used to determine if background software or corrupted system caches are causing the language shift. If Word functions correctly in Safe Mode, you may need to disable conflicting startup items or fonts on your standard user account.

Is it safe to move the Word Container folder to my Desktop?

Yes. Moving the container folder simply forces Word to reset its local preferences and cache upon the next launch. It will not delete your saved Word documents or uninstall the application. You can safely delete the folder from your Desktop once Word runs normally.
