How to Fix Unexpected Proofing and Display Language Changes in Microsoft 365
Question details
Users are experiencing unexpected shifts in Microsoft 365 proofing and display languages, where Word and Outlook use foreign dictionaries or menus despite default English settings.
- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- Typing, navigating menus, or running spell checks in Office applications after a recent automatic update.
- Observed behavior
- English text is incorrectly checked against Spanish, German, or Italian dictionaries, and menus may display in another language due to unprompted language pack installations.
Ensure your Windows operating system language and keyboard layouts are strictly set to English, as Office often synchronizes its proofing language with your active system keyboard.
Remove Unnecessary Language Packs from Recent Updates
Recent Microsoft 365 updates may have automatically installed additional language packs. Removing them is the most effective way to stop unexpected dictionary switching.
Automatic background updates can sometimes push unwanted language packs into your Office installation. Clearing these out will force Word and Outlook to strictly rely on your primary language.
Launch Microsoft Word, click on 'File' in the top left corner, and select 'Options' at the bottom of the menu. Navigate to the 'Language' tab.
Under the 'Office authoring languages and proofing' section, look for Spanish, German, Italian, or any other unexpected languages. Select them and click the 'Remove' button.
In the same window, check the 'Office display language' section. Ensure English is moved to the top and set as preferred. Restart all Office applications to apply the changes.
Disable Automatic Language Detection
Turn off Word's automatic language detection to prevent the spell checker from randomly switching dictionaries based on what it thinks you are typing.
Verify Text-Specific Settings and Keyboard Layout
Ensure your active Windows keyboard layout matches your desired language and that spelling checks haven't been disabled for specific text blocks.
Switch to WPS Office for a Stable, Hassle-Free Experience
If Microsoft 365 updates keep altering your settings and installing unwanted language packs, consider switching to WPS Office. It provides a lightweight, highly compatible alternative with predictable settings, ensuring your documents remain spell-checked exactly how you intend.
- 1. Download WPS Office: Visit the official WPS website and download the free installation package.
- 2. Install and Open: Run the installer. Once finished, open WPS Writer to access a clean, familiar word processing environment.
- 3. Set Default Spell Check: Click on Menu > Options > Spell Check to easily select your permanent default dictionary without interference from automatic systems.
Frequently Asked Questions
Why does Word automatically switch to Spanish or German when I type?
Word features an automatic language detection tool that attempts to guess the language based on your typing. If it misinterprets a word, or if you accidentally press a keyboard shortcut (like Alt + Shift) that changes your Windows input language, Word will switch the active dictionary to match.
Can a Windows update change my Microsoft Office language?
Yes. Sometimes major automatic updates to Microsoft 365 or Windows push newly localized features or additional language packs. This can inadvertently alter your default authoring or display language settings within Office applications.
What does 'Do not check spelling or grammar' actually do?
This is a text-specific formatting option in Word. When applied, it instructs the spell checker to completely ignore the selected text. If you paste text from another source that has this attribute applied, Word will not underline errors in that specific paragraph, regardless of your global language settings.
