Observed behavior
Spelling and grammar errors are not being flagged or displayed while typing, despite the automatic checking options appearing to be enabled in the application settings.

Solution 1Recommended

Verify Spelling and Grammar Preferences

Ensure the real-time proofing features are actively enabled within Word's primary settings.

Sometimes, application updates or minor glitches can cause your proofing preferences to untoggle visually or functionally. Re-confirming these settings is the first step.

1
Open Word Preferences

Launch Microsoft Word on your Mac. Click on 'Word' in the top Apple menu bar and select 'Preferences'.

2
Access Spelling & Grammar

In the Preferences window, locate and click on 'Spelling & Grammar' under the Authoring and Proofing Tools section.

3
Enable Automatic Checking

Ensure the boxes for 'Check spelling as you type' and 'Check grammar as you type' are checked. Close the window to save the settings.

Verify Spelling and Grammar Preferences
Check Document Exceptions: In the same menu, verify that 'Hide spelling errors' and 'Hide grammar errors' are unchecked for your current document.

Frequently Asked Questions

Why did my spell check suddenly stop working in Word for Mac?

This issue is commonly caused by corrupted Word preference files, conflicting third-party add-ins, or accidentally applying the 'Do not check spelling or grammar' setting to the selected text block.

Does resetting Word preferences delete my documents or templates?

No, resetting preferences by moving the container file only clears application configurations and custom settings. Your saved documents and user data remain completely safe.

How do I ensure the correct dictionary is being used in Word for Mac?

Select all your text (Cmd + A), navigate to 'Tools' in the top menu bar, select 'Language', and choose your preferred dictionary. Ensure the 'Do not check spelling or grammar' option is unchecked before clicking OK.
